jenkins cannot parse timestamp in jtl file

Getting Error while the script ran successfully. The JTL file generated previously were not showing any error in parsing time stamp , but now showing like '2021/01/15 14:03:00'

and hence the error showing while parsing. Please review below output and help me out in solving it
