TDateTimePicker internally initialises its DateTime to "Now" - changes to the date-part of the value presumably do not alter the time-part (unless modifying date AND time via the DateTime value). The different time-parts in your pickers presumably reflects different constructor execution times (yielding slightly different Now() results and therefore different time-part values).
Two ways (at least) to skin this particular feline spring to mind: 1. If you only ever work with the Date of these pickers, you could initialise each to a known, consistent time-value (this then shouldn't change unless you subsequently change the time-value in some other way) 2. Specifically exclude the time-part by Trunc()'ing the Date in any comparisons. The Date property itself only does a hard-typecast, not a conversion and since TDate is simply a distinct-type alias for TDateTime this merely propagates and preserves the time-part of the underlying datetime into the supposedly "date only" TDate value. Hope that helps. -----Original Message----- From: delphi-boun...@delphi.org.nz [mailto:delphi-boun...@delphi.org.nz] On Behalf Of John Bird Sent: Tuesday, 29 June 2010 13:42 To: NZ Borland Developers Group - Delphi List Subject: [DUG] DateTimePicker When a TDateTime is set from a DateTimePicker that is being used for Date selections what is set for the time component? Or is it random? I am wondering because two different pickers seem to return unrelated times and it looks like I have to do some testing and correcting. And for testing - I think that a test such as if DatePicker1.date = date then...... might not be a reliable test (if both are effectively floating point) This is D5 in case later versions have smarter testing....
