I took this piece from an unencrypted .DAT file:
Code:
00 e1 27 17 6f e6 69 c0
Which translates to 63,374,851,375,000,000 in decimal. The units for the number are microseconds.
And this huge number cannot bypass the 1st January 1970 00:00:00 format; such a format that most converters use today.
So, yes. Is there such a converter that uses the 1st January of the year 1 format? Or how shall I make one?
And by the way, a timestamp is both date and time.
Thanks in advance!
You do not say what language are you using, if it is a .NET language, you can use: http://msdn.microsoft.com/en-us/library/z2xf7zzk.aspx for that constructor the input is in nanoseconds (are you sure that your number is in milliseconds and not in nanoseconds?).
If you are sure it is in milliseconds, the conversion to nanoseconds should be easy: 1 millisecond = 1 000 000 nanoseconds.
But I have the feeling that those are nanoseconds and not milliseconds...
Now that you have told us that it is in microseconds:
C# Example from decimal to yyyy dd MM hh:mm:ss
long microseconds = 63370738175000000;
long ticks = microseconds * 10;
DateTime timestamp = new DateTime(ticks);
Console.WriteLine(timestamp.ToString("yyyy dd MM hh:mm:ss"));
It prints:
2009 20 02 02:49:35
The other way around from yyyy dd MM hh:mm:ss to decimal
String dateString = "2009 20 02 02:49:35";
DateTime timestamp = DateTime.ParseExact(dateString, "yyyy dd MM hh:mm:ss",CultureInfo.CurrentCulture);
long ticks = timestamp.Ticks;
long microseconds = ticks / 10;
Console.WriteLine(microseconds);
It prints:
63370694975000000
And if you want it in hexadecimal just write:
Console.WriteLine(microseconds.ToString("X"));
Then it will print:
E1234FB3278DC0
If you want the answer in another programming language, please add that to you question.
In JAVA in order to convert microseconds into java.sql.Timestamp:
public static Timestamp getTimestampFromMicros(long pMicros) {
long millis = TimeUnit.MICROSECONDS.toMillis(pMicros);
long shaaritInMicros = pMicros - TimeUnit.MILLISECONDS.toMicros(millis);
Timestamp ts = new Timestamp(millis);
long nanos = ts.getNanos() + TimeUnit.MICROSECONDS.toNanos(shaaritInMicros);
ts.setNanos((int)nanos);
return ts;
}
Use below Java code to covert microseconds to date and time,
long msec = microseconds * 1/1000;
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
dateFormat.format(msec);
Which will returns,

I'm using momentJS to find the difference between two times and format to hh:mm:ss. Ver: "moment": "~2.10.6"
The problem I'm having is an extraneous 7 hours being added to a time whose difference is only 1 minute, 1 second.
var diff_ms = moment('2016-07-29 10:35:18').diff('2016-07-29 10:34:17');
61000
var diff = moment(diff_ms).format('hh mm ss')
"07 01 01"
Convert milliseconds to hours and minutes using Momentjs says to specify the time unit as milliseconds, moment.duration(x, 'milliseconds');, but since it's returning the correct minutes and seconds (01 01), it seems it's correctly defaulting to milliseconds.
I can do this the "un-momentJS" way:
var a = moment.duration(61000, 'milliseconds');
a: n {_milliseconds: 61000, _days: 0, _months: 0, _data: Object,
_locale: l}
var b = a.hours() + ':' + a.minutes() + ':' + a.seconds();
b: 0:1:1
But don't have an easy way of formatting this output to hh:mm:ss using string concatenation like this.
I want to have a string that counts down from current time to alarm time.
I've manage to figer out how to get the current time and how to set the alarm time.
The problem I'm having is that when I take current time - alarm time it gives me a numer witch I then need to format back to a hh:mm:ss string.
i've got this.
set alarmHour to 23
set alarmMinute to 00
set theDate to the current date
set the hours of theDate to alarmHour
set the minutes of theDate to alarmMinute
set the seconds of theDate to 0
theDate
set countdown to theDate - (current date)
set ss to countdown / 60
at this point it gives me 22.283333333333 witch i now need to convert to hh:mm:ss and then put them into a sting that give me 00:22:00
UPDATE:
in swift you have % you can use
countDownTime = (formatterInteger - timeControlInteger)
let interval = Int(countDownTime)
let seconds = interval % 60
let minutes = (interval / 60) % 60
let hours = (interval / 3600)
but how to you do this in applescript?
Answer to second question:
is there a way to format strings like in swift? like
String(format:"%02d",absHour) – Mathias Halén
Yes, but you need to use the Satimage.osax scripting addition, available for free at:
Satimage AppleScript Additions
Satimage strftime() -- Date/Time Format Function
strftime v : format a date using a specification string like in the C
function strftime.
strftime date or list of date
into string : the formatting string. To obtain ISO 8601 dates, use
"%FT%TZ" or "%GW%V-%uT%TZ" (using the 'with GMT' parameter)
[GMT boolean] : if true, output date as GMT. Default: false, the ouput
date is local.
→ string : the formatted date
EXAMPLE: strftime (current date) into “%x” RETURNS: 07/22/14
"%a, %b %d, %Y" RETURNS: Tue, Jul 22, 2014
set d to current date
-- some ISO 8601 formats:
strftime d into "%FT%T%z"
-- "2007-01-15T16:10:56+0100"
strftime d into "%GW%V-%uT%T%z"
-- "2007W03-1T16:10:56+0100"
--if you need to store the date d as UTC:
strftime d into "%FT%TZ" with GMT
-- "2007-01-15T15:10:56Z"
strftime d into "%a, %b %d, %Y %H:%M:%S %z"
-- "Mon, Jan 15, 2007 16:10:56 +0100"
You have been provided the current time as the number of seconds that have elapsed since the start of this century (i.e since the beginning of 2000) as input. You have to compute the date that the input time corresponds to.Note that the output required is an integer in yyyymmdd format where yyyy corresponds to year, mm to month and dd to date.
Note:without using array concept
Example:
currDate(122352353)=20031117 ( it corresponds to 17th November 2003).
long timeInMilliSecs = 122352353000L;
Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("MMM dd yyyy");
try {
cal.setTime(sdf.parse("Jan 01 2000"));
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}// all done
long d = cal.getTimeInMillis() + timeInMilliSecs;
cal.setTimeInMillis(d);
System.out.println(cal.get(Calendar.YEAR) + "" + (cal.get(Calendar.MONTH)+1) + "" + cal.get(Calendar.DATE));
Always work with timeinmillis. This will help you easily convert any date. So first thing is convert your 2000 date to millis and add the given date(122352353 in this case) to it after converting to millis. That is it! Now just convert the milli time to date.
I can't get my head around how formatting a datetime variable inside a string works in PowerShell.
$startTime = Get-Date
Write-Host "The script was started $startTime"
# ...Do stuff...
$endTime = Get-Date
Write-Host "Done at $endTime. Time for the full run was: $( New-TimeSpan $startTime $endTime)."
gives me the US date format while I want ISO 8601.
I could use
$(Get-Date -Format u)
but I want to use $endTime to make the calculation of the timespan correct.
I have tried all permutations of $, (, ), endTime, -format, u, .ToString(...) and .ToShortDate(), but the one that works.
"This is my string with date in specified format $($theDate.ToString('u'))"
or
"This is my string with date in specified format $(Get-Date -format 'u')"
The sub-expression ($(...)) can include arbitrary expressions calls.
Microsoft Documents both standard and custom DateTime format strings.
You can use the -f operator
$a = "{0:D}" -f (get-date)
$a = "{0:dddd}" -f (get-date)

Instead of using string interpolation you could simply format the DateTime using the ToString("u") method and concatenate that with the rest of the string:
$startTime = Get-Date
Write-Host "The script was started " + $startTime.ToString("u")
I am converting the current date to GMT time.
The result is in-consistent, due to this my date time calculations are going worng.
DateTimeFormat df = DateTimeFormat.getFormat("dd MMM yyyy hh:mm:ss");
String gmtStr = new Date().toGMTString().replace("GMT", "").trim();
long deptime= depTime - df.parse(gmtStr).getTime();
deptime = deptime / 1000;
seconds = (deptime % 60);
minutes = (deptime % 3600) / 60;
hours = (deptime / 3600);
Not sure what the best way is, but you could use the getTimezoneOffsert:
final Date gmtDate = new Date();
final Date offDate = new Date(gmtDate.getTime() + gmtDate.getTimezoneOffset() * 60 * 1000);
The offDate when displayed with DateTimeFormat.getFormat(PredefinedFormat.DATE_TIME_LONG) will still show the utc/gmt offset, because basically you have create a new time in the current timezone, but it matches the time of the GMT time and the long value returned from getTime() will be the number of milliseconds you can use in your calculation.
