I have cells with dates in this format: DD/MM/YYYY 00:00:00 and I want to add 3 hours because I'm in a different GMT zone.
Is possible to use dates in a formula?
Something like: 30/12/2012 22:15:00 should become: 31/12/2012 01:15:00

All date/time values in spreadsheets are internally handled as floating point values. To add 3 hours to a date/time just add (3/24) to the original date/time.
=F3+(3/24)
This also works in MS Excel.

Thanks, I did't knew that... One more thing, I'm using importrange to brin that dates... And I can't figure out how to do it with that...
=importrange("xxxMyKeyxxx";"Archive!E2:E")... Where should I add "+(3/24)"? Thanks again– SantiagoJul 11, 2012 at 22:14 -

See also: Convert a date in Google Spreadsheet?
=A1+Time(3,0,0)
Adds 3 'Hours', 0 'Minutes', 0 'Seconds' to the date/time value of A1
Additionally if only you use the main sheet you can go into the sheet settings and change it's timezone accordingly.
I do this for my work schedule to track different projects:
Three columns A B C where column A is text, B is hours, C is minutes.
In Time 8:00 AM is B2
WLI 3 15
ADMS2 2 0
O&M 2 30
Break 0 15
Total 7 45
Out Time 3:45 PM
Total: =SUM(B3:B6) for hours, =SUM(C3:C6) for minutes
Out Time: =SUM(B2,(B7+C7/60)/24)

There is help available for the editor. Just click the question mark to the upper right of the editor. In this case, though, with tabular data, code format works reasonably well.– aleJan 7, 2014 at 16:46
3 hours are equal to the value of 0.125, therefore shortest formula would be:
=A5+0.125
