[Asterisk-Users] ${EPOCH} and ${DATETIME} patch

[John Todd]

This is actually fairly useful.  I did the equivalent (again, for a 
filename like you did) with an AGI.  Here is my method below.  It's 
less elegant (requires an AGI call every time) but more flexible 
(uses the Linux built-in "date" program to produce any number of 
variations on date/time).  I suppose a quick extension could be 
written into the AGI to also specify the time/date format, but I 
didn't get that fancy with this version.

Contents of the file /var/lib/asterisk/agi-bin/set-timestamp.agi:

#!/bin/sh
longtime=`date +%Y%m%d-%H%M%S`
echo SET VARIABLE timestamp $longtime

;(snippet from extensions.conf)
;Now, I call the AGI:
exten => s,1,AGI(set-timestamp.agi)
; and the results are set in $timestamp
exten => s,2,SetVar(CALLFILENAME=${timestamp}-${ARG2}-${ARG1})
