Hi Rajesh,
This internal date format on Provisioning Directory is an internal Julian date in "0000YYYDDD" format.
YYY is the year - 1900.
DDD is a 3-digit Julian day within the year, with leading zeros (day-of-year starting with 1).
e.g.:
YYY=2017-1900=117
DDD=27th Nov=331
Many documentations exist on the web explaining on how to play in a program code with such a format.
Regards,
Philippe.
