Sybase point in time load fails with The specified recovery date in not between error

When I run a sybase point in time load. Backup server reports this error

000'The specified recovery date (Nov 5 2014 8:55:00:000AM) is not between the start (Nov 5 2014 7:48:29:530AM) and end (Nov 5 2014 8:52:13:890AM) date.

Where does backup server get this times from?

Are there any tables in sybase server which stores the time when a dump was taken?

Please let me know if there are any views or tables I can check.

Thanks

Shankar
