[asterisk-users] Asterisk dialplan date and time operations

Discussion:

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

If you'll be using call files to do this, you can 'touch' them to a
future date and Asterisk will not act on them until that date is reached.

Thanks Doug.
Yes. Thats what I plan to do and allready knew about. But I want to know
wether there is an easy option to operate with times (add x minutes to a
time) or not? My research until now wasn't successful and I'm wondering that
nobody before had this problem... (date and time manipulation)
Cheers,

Erik

There is not. However, if you convert your time to seconds, then it's
naturally easy to do math, and you can then convert the format back.
You can use the dialplan functions STRPTIME() and STRFTIME() to help you
with the conversions.

daveC,

No it's even simpler. ( I dont need an IF case)
I just want to add e.g. 15 minutes to the current date / time:

So simply said:

${STRFTIME(${EPOCH},,%Y%m%d%H%M)} + 15 minutes!

My question was how can I do that.? Of yourse e.g. if it's 23.57 pm and I add
15 minutes the day should increase +1 and the hours start with 0:x the
minutes with 12 ( and not 72 as the normal addition would result).

Kind Regards,

Erik

erik,
cool, there are so many functions in *, it takes a long time to learn
the shortcuts!
thanks erik!

Thanks!

I got it now!

Here is a sample for a delayed callback after a caller gets to a users
voicemailbox. Purpose: Reminder for people that they got a message on their
v. box.

exten => 1002,1,Answer
exten => 1002,2,Set(CHANNEL(musicclass)=default)
exten => 1002,3,Queue(test|t|||5)
exten => 1002,4,Voicemail(b1205)
exten => 1002,5,System(echo -e "Channel: SIP/we-static\\nCallerID:
VOICEMAIL
<8500>\\nContext: test\\nExtension: 444" > /tmp/${UNIQUEID}.call)
; add 15 minutes (in seconds 900) to the epoch time
exten => 1002,6,Set(newepoch=${MATH(${EPOCH} + 900 |int)})
; write it out for debugging purpose
exten => 1002,7,NoOp(${newepoch})
exten => 1002,8,System(touch -t ${STRFTIME(${newepoch},,
%Y%m%d%H%M)} /tmp/${
UNIQUEID}.call)
exten =>
1002,9,System(mv /tmp/${UNIQUEID}.call /var/spool/asterisk/outgoing
/)
exten => 1002,10,Hangup

Kind Regards,

Erik
