[Gambas-user] arithmetic operations on dates and times

[Jussi Lahtinen]

I'm not sure I understand correctly, but this code adds one year to current
date and prints it.
Print Date(Year(Now) + 1, Month(Date), Day(Now), Hour(Now), Minute(Now),
Second(Now))

But I don't know what is upper limit of accepted year.
Maybe you want to use integer or even long variables instead to hold your
time values.
