| Description |
The IncHour function returns a TDateTime value that is NumberOfHours greater than the passed StartDateTime value.
The year, month, day and hour values are incremented as appropriate.
The increment value is optional, being 1 by default.
|
|
| Notes |
There is no DecHour function.
Instead, use IncHour with a negative increment.

| Example code : A simple example of increment and decrement |
var
myDate : TDateTime;
begin
// Set up our date just before the end of the year 2000
myDate := EncodeDateTime(2000, 12, 31, 23, 0, 0, 0);
ShowMessage('myDate = '+DateTimeToStr(myDate));
// Add 10 hours to this date
myDate := IncHour(myDate, 10);
ShowMessage('myDate + 10 hours = '+DateTimeToStr(myDate));
// Subtract 10 hours from this date
myDate := IncHour(myDate, -10);
ShowMessage('myDate - 10 hours = '+DateTimeToStr(myDate));
end;
