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
Google Spreadsheets: Add 3 hours to Date value (DD/MM/YYYY 00:00:00)
google spreadsheets;date
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.
