I even faced the same problem, hence tried deleting and re-creating the backup Job.
It displayed the time correct, however next day it was the same. Checked the Time Configuration on the ESXi host and it was in Sync.
Logged in to the putty session:
Checked for any active backup using the command:
mccli activity show --active
No backups were running, hence stopped and started all the services using the below command and then rebooted the appliance
dpcntl stop all
dpnctl start all
There were some gsan errors which got fixed and there after the job is working fine as expected.
Possibly some issue with tomcat services? If MCS is out of sync with tomcat then the GUI would report one thing and the CLI would say the other.
Perhaps upgrade this to 6.1.x as they have newer java releases.
