How to Convert DateTime to Date ?

Question

This sounds easy, but I'm not progressing as I should.
     element MyDate : Date;
     MyDate = contract.ValidityPeriod.TimePointPeriod.StartTimePoint.DateTime. ;
The above complains about "Assignment of type DateTime to type Date is not possible".
I've looked into DateTime functions, but am not getting anywhere.
Any tips on how to convert a DateTime field to Date field ?

Answer 1

Afaik, AP.Common.GDT.DateTime does not have a ConvertToGlobalDateTime method, furthermore retrieving the date from the globalDateTime could give you the wrong local date since it does do not consider time zones.
I would use the similar to the following (no guarantee about correctness):
import ABSL;
import AP.Common.GDT;
var In = contract.ValidityPeriod.TimePointPeriod.StartTimePoint.DateTime;
// convert To GlobalDateTime
var timeGlobal = GlobalDateTime.ParseFromString(In.content.ToString()); // not sure whether this is correct -> please verify yourself
// convert to LOCAL_DateTime using timeZone
var timeZone = In.timeZoneCode;
var localDateTime = timeGlobal.ConvertToLocalDateTime(timeZone);
var localDateTimeStr = localDateTime.ToString();
// cut off time suffix (starts with "T")
var localDateStr = localDateTimeStr.Substring(0, localDateTimeStr.Find("T"));
var date = ABSL:Date.ParseFromString(localDateStr);
