Date/Time Validation - Request Off Form

CurrentDate reference always evaluates to date up to midnight. 

so this formula 

If Today's Date = 01/14/2019 10:00 AM, then Request Start Date = 01/14/2019 09:00 AM should be invalid.

cannot consider time

second formula

If Request Start Date = 01/15/2019 10:00 AM, then Request End Date = 01/15/2019 08:00 AM should be invalid. 

should work.

but note that change of hours or minutes doesn't trigger validation formula to be reevaluated. it only reevaluates if you change date part or submit form

Thank you for your response. 

      "note that change of hours or minutes doesn't trigger validation formula to be reevaluated. it only reevaluates if you       change date part or submit form"

Are there any methods to have the hours and minutes to trigger the validation formula? 

not at all on responsive forms.

but is that really necessary?

validation formula is triggered on submit. so if dates are not valid on submit you'll not be able to save the item.

I know, user experience is not pleasant if they see validation error on the form despite inputs are correct. but that's unfortunately how it's work.

Euan Gamble‌, what's your opinion on that? should hour/minute change trigger validation formula to recalculate?

... especially to clear validation error once inputs are corrected.

Hi Marian Hatala‌

With Universal Forms, we validate the date and time together if you have chosen to show the Time component. This will validate on submit.

In our current iteration of Universal Forms, the only missing component is the ability to select a control or variable to compare against in the rule builder which we have planned.

Cheers,

Euan
