Please anyone advice me the way to escap run-time variables in freeradius. I am using STR_TO_DATE and freeradius run-time variable is over-riding the mysql time variables

SELECT STR_TO_DATE('14 Mar 2012 21:37:23','%d %M %Y %H:%i:%s') gives 2012-03-14 21:37:23 in MySQL

Whereas in freeradius

SELECT STR_TO_DATE('14 Mar 2012 21:37:23','%d %M %Y %H:%i:%s') gives

'14 0 2011 20:001122334455:_

14 = Current Date

0 = MTU

2011 = Current Year

001122334455 = Calling-Station-ID

_ = Speed

I have tried escaping as per the thread http://freeradius.1045715.n5.nabble.com/Changing-the-format-of-a-date-attribute-tt2775323.html#a2775328

But no luck ..

Thanks in advance !!
