Using
TDateTime
Explains how to set Date and Time.
TDateTime()
The example below shows how to construct
a TDateTime object, initialising it to midnight 6th January
1996;
TDateTime dateTime(1996,EJanuary,5,00,00,00,000000);
Set()
When setting the day and month, subtract
one because the ranges are offset from zero. For example, to set the date
to 31st December 1996:
TDateTime dateTime;
TInt year=1996, month=12, day=31;
dateTime.Set(year,TMonth(month-1),day-1,0,0,0,0);
