Can you use server side validation to ensure one date/time is greater than another?

Hi All,

Just like the title suggests, I can’t seem to find a way to use server side validation to ensure an ‘end time’ is greater than or in the future compared to a ‘start time’

Naturally i can use front end dynamic mins and maxs, to limit the input, but that isn’t the same as validation.

None of the options i’ve tried in Server Connect seem to work.

Any ideas?
