xymond error state - invalid timespec.

Good morning, Xymon team.

Running Xymon 4.3.28, I've recently started receiving yellow alarms for xymond with the following:

Latest error messages:
Invalid timespec - expected 4 digits, got: '03'

Does this look familiar to anyone and, if so, what do I need to do to fix it?
