Hello everybody,
how can I reduce e.g. 30 days from a date?
When I do the following "2011-05-01 CEST" -"2011-04-01 CEST" I get:
"Time difference of 30 days"
an thats fine.
But when I try "2011-05-01 CEST" - 30 I get nonsense.
So how can I subtract some days, month or years from a date?
thanking you in anticipation
Claudia Paladini
