Calculating time difference in Asterisk

Hello experts,

In Asterisk I have a specific time stored in the db, and I have the following dial plan:

exten => 123,1,GotoIf(CONDITION?TRUE:FALSE)

CONDITION shall be TRUE if the time difference between the stored db time and the current time  is less than one hour.

Would anybody please provide the required condition code?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

What format is the time in?
You will first want to read the time out of the database into a variable. Then if it is not in epoch format convert it using http://www.voip-info.org/wiki/view/Asterisk+func+strptime

Epoch is measured in seconds so assuming ${dbval} holds the db value in epoch format you can use the following as the condition.
$[${EPOCH} < (${dbval}+3600)]
