I have an agent Container, which has a parameter departure_date. I want to generate random future dates for this parameter. The date should be between current date and next 30 days. How can I achieve this?
Thank you in advance.
It is not clear whether your parameter is of type Date or double. I'll provide you with a solution for each case.
Date
departure_date = addToDate(date(), DAY, random()*30);
Double - assuming your model time unit is DAYS
departure_date = time() + random()*30

I would like to create two variables as the production date and expiration date for my agent "Product" in AnyLogic and then compare the expiration date to the current date of the model to find out if it's expired.
I modeled the variables as Date:
Date productionRDate;
Date expirationRDate = addToDate(productionRDate, DAY, 30);
and compare expirationRDate to the current date like this:
differenceInCalendarUnits(DAY, agent.expirationRDate, date()) > 0
and initialized productionRDate as in the image below. But it has an error that says:
initialization and the error
Any suggestion on what should I do?
Thanks a lot.
You need to initialize productionDate as well, it is currently empty, so you cannot add to it.
Do something like
Date productionDate =date();
It needs to have a value
I have to calculate the number of days between two dates and I search and I don't find any similar function available in ADF.
what I've noticed so far is that if I want to get the number of days between 2 columns, it means that the columns must be date columns, but I have timestamp columns (date + time)
how can I transform these columns into Date columns? or do you have other idea?
Using the fact that 86,400 is the number of seconds in a day
Now, using the function
ticks,
it returns the ticks property value for a specified timestamp. A tick
is a 100-nanosecond interval.
#string(div(sub(ticks(last_date),ticks(first_date)),864000000000))
Can re-format any type timestamp using function formatDateTime()
#formatDateTime(your_time_stamp,'yyyy-MM-dd HH:mm:ss')
Example:
#string(div(sub(ticks('2022-02-23 15:58:16'),ticks('2022-01-31 15:58:16')),864000000000))
This is the expression that I used for Data Flow.
toDate(toString({max_po create date},'yyyy-MM-dd')) - toDate(toString(max_datetimetoday,'yyyy-MM-dd'))
max_po, create date and max_datetimetoday are TimeStamp(date + time) columns.
The result is in days.
I have this doubt on how to compare DB2 date, time fields with RPG date and time fields
If (Zpschdt < CurDat or (ZPschdt = Curdat and
(%Time() - ZPschtm) > 30));
For example in the above piece of code, Curdat is a character field which contains date value populated using below line
CurDat = %CHAR(%DATE():*MDY);
%Time() that is the current time needs to be subtracted from ZPschtm which is a DB2 time field and needs to be checked if the difference is greater that 30 minutes. How can this be achieved?
You can't compare a character variable to a date variable.
Generally, you have to either convert the character to date, or the date to character.
Since you character variable is formatted *MDY, it'd be easier to convert it to date; otherwise you'd need to change the format to YYYYMMDD in order to compare it as a numeric or character.
If Zpschdt < %Date(CurDat:*MDY)...
If you want to find schedule dates and times that are more than 30 minutes old, and the timeframe needs to cross days, you are going to have to use timestamps rather than dates and times. To deal with your situation, define a timestamp field, assign the schedule date and time, add 30 minutes to the timestamp, and compare that to the current timestamp. Like this:
dcl-s ts Timestamp;
ts = zschdt + zschtm + %minutes(30);
if ts < %timestamp();
// do something here
endif;
Think I have found a good enough solution for this as below:
If ( %Diff(%Date():Zpschdt:*Days) > 1 or
(%Diff(%Date():Zpschdt:*Days) = 0 and
%Diff(%Time():ZPschtm:*Minutes) > 30));
The first condition of Or - %Diff(%Date():Zpschdt:*Days) > 1 checks if Current date is ahead of the change date at least by one day.
The Second condition :
(%Diff(%Date():Zpschdt:*Days) = 0 and
%Diff(%Time():ZPschtm:*Minutes) > 30))
checks if the Change date is same as current day and if Current time is ahead of change time by at least 30 minutes..
Does this look good enough? Seems to do the job..
I have a date that is stored as a number that is 201401. I would like to subtract 1 month, so that is 201312 and not 201400.
Also, if there is a more efficient way, please suggest as well. I also have the date stored as 01Jan2014, and would be fine converting the SAS date at that point, so that I can create two new columns (with 1 month subtracted) so that they have the value 01Dec2013 and 201312. Also, a function for incrementing the month forward or backward would be much appreciated.
Thanks in advance.
If you store the date as a SAS date, you can use the function intnx to increment it by whatever period you like.
newdate = intnx('Month',olddate,1,'s');
If you store it as an integer like your original, you're on your own to figure that out. My answer: don't.
The prior answer works.
I just wanted to add, storing as Date in SAS is not the same as storing as integer. It may display 01JAN2014 but it represents a number, so you can still perform computations.
If you store the date as a SAS date, you can use the function intnx to increment it by whatever period you like.
newdate = intnx('Month',olddate,1,'s');
I have a data set in which month and year are in one variable and come in the form 200801 which equates to 2008, January. How can I create a SAS date from this integer?
I would like something in the form of Jan 2008 - anything so that SAS recognizes it as a date, as I then need to subtract this value from service date to find out how much time has elapsed since enrollment into the dataset until date of service.
Please also keep in mind that this is a variable, and I have thousands of observations. So I also need the data step/ function to do this for the entire variable.
Any help is appreciated!
You need to put it to a character variable, then input back to numeric. You can do that pretty easily.
date_var = input(put(date_var_orig,6.)||'01',yymmdd8.);
You can also do it this way:
date_var = mdy(mod(date_var_orig,100),1,floor(date_var_orig/100));
Both assume you want the day to equal 1; make a choice there if you want something else (like end of month or middle of month).
