The error output is:
2020/12/10 07:58:01 ERROR: The last backup `2020-12-10-12-33-01.722470' happened in the future.
ERROR: An error was encountered during submission
Fatal Error: Backup error
The code here seems to be the offending part - https://github.com/apple/foundationdb/blob/6.2.19/fdbclient/FileBackupAgent.actor.cpp#L3600
Am I correct in my understanding that the lastBackupTimestamp is being stored without any timezone info, hence causing this bug?
