[asterisk-users] Asterisk dialplan date and time operations

[Erik Wartusch]

Hi all,

Im using Asterisk 1.4.11 and I want to proceed some time and date operations 
in my dial plan. (for a time shifted callback).

Should look like:

CURRENT TIME + x minutes.

Of course it should increase the hours for example in this case:

10.59 + 5 minutes = 11.04

I guess I've to use the math function in 1.4 but how can I manage easily the 
time operations?

Kind Regards,

Erik
