integer (milliseconds) or in HH:mm/HH:mm:ss format." +

this case 'Time Adjustment' value should be -05:00:00 or 18000000." +

Server is hosted in UTC, the value should be 05:00:00 or 18000000." +

requires manual re-adjustment in this case."

Review comment:
I think it's actually better for anyone who reads to code to see the
validation expression right here in the validator.
