> *Problem Statement:* Currently Ranger usersync group modifyTimestamp parsing is in 12
hours format. (not sure its as per the requirement or by mistake). for the parsing date format
is choosen as "yyyyMMddhhmmss" where hh can convert hour value to 12 hours format. for example:
if a group is synced at 00:05am UTC then this will highest user sync time stamp but after
the conversion value becomes 12:05 which is actually future timestamp and for the next 12
hours delta sync of groups may not sync any groups. 
> *Proposed solution:* Conversion should be done in 24 hours format by using hours in HH
format rather hh.
> *Note:* 1) To reproduce this issue frequently i have to switch my default ldap delta
sync interval to 5  minute as compare to 1 hour.
> 2) I am not sure about the current behaviour of different ldap servers and AD without
this patch. some might be working so i request reviewers to add their feedback on this.
> 3) It will be better if reviewers can test this patch in their environment and share
 their experiance here or on the jira.
