Hi, Try to download my cDateTime.zip at:

My View on DateTime is Date + Time.....

CarryDate = TTOD(WholeDateTime)
LeftTime = WholeDateTime - DTOT(CarryDate)
* As take zero on time when transform

So, you can do it separately!

Thanks, David. I have put some of his Date Control feature on it..
Such as YeaR, MontH for 1st day of year, month....

2nd, You can directly Add or subtract a digit on DateTime or Date!!

e.g. {1998/11/17} + 1 == {1998/11/18} !!
and {1998/11/17 03:05:44} + 1 == {1998/11/17 03:05:44}

That is:
to Hour +1 or -1, Use 3600 to add/subtract
to Minute +1 or -1, Use 60 to add/subtract
to Second +1 or -1, Use 1 to add/subtract

Of cos, you can use 86400 for a Day... but a little bit crazy! ~_^

After you divide DateTime into Date and Time...
Everything is happy and you can control it easily...

For more funny feature on it... pls download cdatetime.zip
and see.... hee hee. I have 'N' std for Noon Function..
that is reset the leftTime to 43200...
Therefore, it can assign datetime with easy!

p.s. this is designed for having controlsouce, if no, try DateTime() as
controlsource to test..
