Author: tilghman

New Revision: 369940

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=369940
Log:
Allow the REALTIME() function to report errors back to the caller.

Also, do more error checking on the arguments specified to the REALTIME()
function and clarify the documentation.  While I was editing the file, a
few coding guidelines fixups, as well.

Review: https://reviewboard.asterisk.org/r/2031/
