MapR service ticket expiring one day before date expiry date?

We had created a service ticket(by first creating mapr user ticket) on MapR cluster nodes  using the following link as reference : Tickets and Certificates - MapR 5.0 Documentation - . We had provided the duration of the service ticket in seconds. maprlogin generateticket -user mapr -type service -out /tmp/longlived_ticket -duration <duration in seconds>.  The mapr print ticket command for this yielded the following output:

xxxx.xxxx.xxxx: user = xxx, created = 'Thu Dec 14 21:08:18 PST 2017', expires = 'Sat Jan 13 21:08:18 PST 2018', RenewalTill = 'Wed Mar 14 22:08:18 PDT 2018', uid = nnn, gids = nnn, CanImpersonate = false

However, we are seeing that when we use this ticket, simple cluster hadoop calls are failing right now, but the same ticket was working 2 days back. Is the service ticket expiration date approximate in nature, and the ticket has actually expired?


NOTE: we have ensured that MAPR_TICKETFILE_LOCATION is exported correctly and that ticket is present at that path.
