Question

I am programming in Delphi and consuming an API that returns an XSDateTime representing an appointment timeslot. When I try to create a local datatime the time is being converted to my EST timezone (Z-05:00 or Z-04:00 depending on DST). I need the time to remain in the original timezone of CST (Z-06:00). I am currently formatting the time as follows:

aApptListing := FormatDateTime('yyyy/mm/dd t', aSlots[i].StartDateTime.AsDateTime);

where StartDateTime comes in as the time in CST (Z-06:00). How can I keep the original time for CST? For instance, if the date/time comes thru the API as ‘2011-12-25T08:00:00-06:00’ I want to show 12/25/2011 @ 8:00 AM, not 9:00 AM which would be EST.

Answer 1

It looks like the following should work:

with aSlots[i].StartDateTime do
  aApptListing := FormatDateTime('yyyy/mm/dd t', EncodeDateTime(Year, Month, Day, Hour, Minute, Second, 0));
