What is the problem? Please be detailed.
Hi. I need to set a date field with a date that it must be before the 01/01/2000 for saving time in the selection of year. Is there a way to made it?
Greetings from Guatemala
If you want an input where the date entered must before some particular date - eg 01/01/2000 - then you can put a constraint on the input, and use the decimal-date-time() function to ensure it meets your specified condition.
decimal-date-time(dateTime)
Converts dateTime value to the number of days since January 1, 1970 UTC. This is the format used by Excel.
eg
constraint = decimal-date-time(${mydate})<10957
[there are 10957 days between Jan 1 1970 and 2000].
Is that what you are after?
@Xiphware, I think you can simplify the constraint and use: . < date(01/01/2009). I haven't tried it, but it should work!
Good point. But might need . < xs:date('01/01/2000') to disambiguate from ODK date(), which wants an integer argument.
