How can i ParseExact Wed Jun 27 08:50:00 2018 -0500 - powershell

Im trying to use [datetime]::ParseExact
The string i need to convert to datetime is Wed Jun 27 08:50:00 2018 -0500
I couldnt figure out the correct format to convert it correctly.
Please help me out. Thanks


Try this as well:
$Date = 'Wed Jun 27 08:50:00 2018 -0500'
[datetime]::ParseExact($Date,"ddd MMM dd HH:mm:ss yyyy zzz",[CultureInfo]::InvariantCulture)


There are several options. To some extent it will depend on what you want to do with that time offset. Here is one way that ignores the offset:
$test = 'Wed Jun 27 08:50:00 2018 -0500'
$parts = $test.split(' ')
$date = get-date ('{0}{1}{2} {3}' -f $parts[2], $parts[1], $parts[4], $parts[3])

Parse DateTime with abbreviated weekday name in Powershell

I get a Date in the following format from an api:
Mon Apr 29 14:40:17 2019
I try to parse it to a valid powershell Date with the following command:
$test = [DateTime]::ParseExact("Mon Apr 29 14:40:03 2019", "ddd MMM dd HH:mm:ss yyyy",$null)
Powershell returns "Exception calling "ParseExact" with "3" argument(s): "String was not recognized as a valid DateTime."
It seems that the problem occurs because of the abbreviated weekday format. If I remove "Mon" and "ddd" the parse works.
The information about the Format specifier is from: https://learn.microsoft.com/en-us/dotnet/standard/base-types/custom-date-and-time-format-strings#dddSpecifier
Anyone knows what causese the error?

Replacing $null with [System.Globalization.CultureInfo]::InvariantCulture solved the problem.
The working code is:
$test = [DateTime]::ParseExact("Mon Apr 29 14:40:03 2019", "ddd MMM dd HH:mm:ss yyyy",[System.Globalization.CultureInfo]::InvariantCulture)

Change date format 08 / 03 / 2017 to 08 March 2017

I'm trying to change date format from 08/03/2017
08 day
03 Month
2017 year
I I'm using
date("d F Y", strtotime($date));
the problem is that I Get 03 August 2017 instead of 08 March 2017
PS : I can't use any other then
dd/mm/yyyy

Try this
$date = DateTime::createFromFormat('d/m/Y', "08/03/2017");
echo $date->format('d F Y');
You can check it to http://php.net/manual/en/datetime.createfromformat.php

After Some researchs I found a solution
str_replace(' / ', '-',$date)

/*
You got August because you provide wrong format to this function. Function accept m/d/y and you provide d/m/y. you can try with this format m/d/y
or
you can try this with DateTime object.
*/
$date = "08/03/2017";
$dateObject = DateTime::createFromFormat('d/m/Y', $date);
echo $dateObject->format('d M Y');

Automatically put working week

Right now i am working on a weekly basis gathering the data and put the week and month manually. For example: The working week for today this week is June 23 thru June 29. and the month is June 2014.
I want to gather the YTD data and based on the date put the Week and Month automatically
For example:
Referral Request Date Week Month
1/3/2014 0:00 December 30 thru January 05, 2014 January 2014
1/3/2014 11:10 December 30 thru January 05, 2014 January 2014
12/31/2013 0:00 December 30 thru January 05, 2014 December 2013
6/18/2014 0:00 June 16 thru June 22, 2014 June 2014
6/20/2014 9:51 June 16 thru June 22, 2014 June 2014
4/28/2014 16:34 April 28 thru May 04, 2014 April 2014
5/1/2014 15:22 April 28 thru May 04, 2014 May 2014
The working week will begin each monday and finished on Sunday.
It can be do automatically?? The file have thousand of lines...

Here you are:
#!/usr/bin/perl
use strict;

use feature 'say';

use DateTime::Format::Strptime;
my #datetimes = (

);
for my $datetime_str (#datetimes) {
my $strp = 'DateTime::Format::Strptime'->new( pattern => '%m/%d/%Y %H:%M' );
my $dt = $strp->parse_datetime($datetime_str);
my $month_year_strp = 'DateTime::Format::Strptime'->new( pattern => '%B %Y' );
my $month_year = $month_year_strp->format_datetime($dt);
my $desired_dow = 1; # Monday
$dt->subtract(days => ($dt->day_of_week - $desired_dow) % 7);
my $month_day_strp = 'DateTime::Format::Strptime'->new( pattern => '%B %d' );
my $monday = $month_day_strp->format_datetime($dt);
$dt->add(days => 6);
my $sunday = $month_day_strp->format_datetime($dt);
say "$datetime_str, $monday thru $sunday, $month_year";
}
Next time help someone else (in case this is what you're after -- I am not sure if I got your question). :-) I used the link posted by #scragar in comments.

How do I set the timezone for Perl's localtime()?

In Perl, I'd like to look up the localtime in a specific timezone. I had been using this technique:
$ENV{TZ} = 'America/Los_Angeles';
my $now = scalar localtime;
print "It is now $now\n";
# WORKS: prints the current time in LA
However, this is not reliable -- notably, if I prepend another localtime() call before setting $ENV{TZ}, it breaks:
localtime();
$ENV{TZ} = 'America/Los_Angeles';
my $now = scalar localtime;
print "It is now $now\n";
# FAILS: prints the current time for here instead of LA
Is there a better way to do this?

Use POSIX::tzset.
use POSIX qw(tzset);
my $was = localtime;
print "It was $was\n";
$ENV{TZ} = 'America/Los_Angeles';
$was = localtime;
print "It is still $was\n";
tzset;
my $now = localtime;
print "It is now $now\n";
$ perl -v

I'd strongly suggest using a module to do this. Specifically, I'd suggest using DateTime (see Perl DateTime Wiki or CPAN
Then you should be able to do something like the following:
use strict;
use warnings;
use DateTime;
my $dt = DateTime->now(); # *your* local time assuming your system knows it!
my $clone1 = $dt->clone; # taking a copy.
$clone1->set_time_zone('America/Los_Angeles');
print "$clone1\n"; # output using ISO 8601 format (there a lot of choices)
print "$dt\n";

Whilst your code works fine for me on both Linux (Perl 5.10.0) and MacOS X (5.8.9), there is a possible solution.
The underlying C functons used by Perl (ctime(), localtime(), etc) call tzset() the first time they're invoked, but not necessarily afterwards. By calling it yourself you should ensure that the timezone structures are correctly re-initialised after any change to $TZ.
Fortunately this is easy - the tzset() function is available in the POSIX module:
#!/usr/bin/perl -w
use POSIX qw[tzset];
$ENV{'TZ'} = 'Europe/London';
tzset();
print scalar localtime();
NB: some Google searches suggest that this is only necessary with Perl versions up to and including 5.8.8. Later versions always call tzset() automatically before each call to localtime().

use Time::Zone;
my $TZ = 'America/Los_Angeles';
my $now = scalar localtime time() + tz_offset($TZ);
print "It is now $now\n";
seems to work here. (The 'scalar' is redundant here since $now gives it scalar context, but it's also nice to be explicit.)
As per the comment, I got the original problem. This seems to fix it for me, but given that others aren't having the original problem, the "seems to work here" bit is intended as an invitation for those people to try this solution as well to ensure it doesn't break anything. (I have to wonder if alnitak noticed the difference between what I posted and the original post?)

Expanding on BrianP007 answer you use both TZ and _tzset
$was = localtime;
print "It was $was\n";
$ENV{TZ} = 'CST6CDT'; # America/Chicago
Time::Piece::_tzset(); # Local time is now Chicago Time
$was = localtime;
print "It is $was\n"; # Right now in Chicago
The trick is the TZ is set from your location to GMT. So normally you would think Chicago is UTC-6, but from Chicago it is 6 hours to UTC which = 'CST6'.
See http://science.ksc.nasa.gov/software/winvn/userguide/3_1_4.htm

Executive Summary:
Setting $ENV{TZ}='/*&+000000000005' and calling Time::Piece::_tzset() fixes localtime() to agree with the windoz system clock.
Sanguinarily gory details:
On Strawberry Perl, windoz 7/64, none of the "Standard" time zones works in the TZ environmental variable to localize localtime(). 'America/Chicago' gives exactly the same time as 'America/Los_Angeles' == 'CDT' == 'CST' == 'UTC' == '-01:00', etc. The list is infinite.
Every timezone on http://www.timeanddate.com/time/zones/ that I tried gives the right time if you are in Greenwich.
Every time from: http://en.wikipedia.org/wiki/List_of_tz_database_time_zones
also fails to change localtime() at all. And, there is no apparent indication. They do nothing and say nothing.
There is NO tzset() on windoz:
POSIX::tzset not implemented on this architecture
There is not even any concept of POSIX ???
C:\bin>cpan install POSIX
...
Warning: Cannot install POSIX, don't know what it is.
Try the command i /POSIX/
It appears to be baked into win8 and there are some dot NOT libraries for it.
For Austin, Texas, in the very Center of Central Intergalactic Time, thee correct $ENV{TZ} which gives me a scalar localtime() which ~agrees with the o/s level time function and the windoz clock is:
'/*&+5' !!! Yes Slash-Star-Ampersand-Plus-5 works!
P:\br1\sxsw.2015\sx-2015.0318\done>time
The current time is: 16:36:39.44
...
Time=Apr 14 16:36:42 2015, ENV->TZ=/*&+5
By running a for loop and trying random values from various posts, for Strawberry Perl uname='Win32 strawberry-perl 5.18.2.2...' with known timezone bugs, any 3 chars I tried (didn't try + or -) followed by +/- and a small number worked. Here is an array of text values and their output below:
use Time::Piece;
#tz = ('', 'CDT+5', 'CST+5', 'FKU+5', 'XYZ+5', '+5', '+05', '+05.00',
'America/Chicago', 'America/Los_Angeles', 'CDT',
'CST', 'UTC', 'PDT', 'PST', '-01:00', '+01:00', '-05:00'.
'ACDT', 'EASST', '5000', '+0500', '+5:00', '+05:00', 'SSS+1', 'SSS+0',
'zzz-1', 'ZZ1+5', '123+5', '___+5', '/*&+5', , '/*&+05', '/*&+005',
'/*&+000000000005');
foreach $tz (#tz) {
$ENV{TZ} = $tz if $tz;
Time::Piece::_tzset() if $tz;
printf("T%s, ENV->TZ=%s\n", scalar localtime, $ENV{TZ} || 'NoTZ');
}
Most every try with anything but XXX . +|- . integer gave UTC, but many were an hour off for no reason (America/Los_Angeles and America/Chicago gave the same value). I am almost sure I used to get away with just CDT and CST, possibly on Activestate (switched to Strawberry to compile my own Perl modules rather than rely on Activestate for everything). This is the first major snarl.
I rebuilt DateTime from scratch and it worked fine. DateTime::TimeZone::Local::Win32 "failed for 'Win32::TieRegistry'"
Here's the sorted result of the attempted zones above:
