Can't schedule backup before 10:00 AM

Summary

When I set a DB_DUMP_BEGIN value without four digits (500), I get an error "_BACKUP_BEGIN is invalid - Unable to perform scheduling". If I set it to 0500, I get the same error. It doesn't seem to like the leading zero.

Steps to reproduce

Do the normal setup for dbbackup configuration.
Set the value for DB_DUMP_BEGIN to 0500 (or any other value before 10 AM)
Start the container.

What is the expected correct behavior?

Should correctly schedule the backup and run the backup at the specified time.

Possible fixes

I suspect this is probably just a one-off parsing error. It may also be that I'm misunderstanding the error message.
