The DateTime widget doesn't allow you to restrict the selection.

Regarding validation, there isn't a simple function to use, but I can think of two ways

#1 - define a time period to match your schedule. Then use the working_hours.EffectiveDuration function with the time selected and the time selected + a small interval (of let's say 1 minute, or even less). If the value returned by the function is the same as your interval, you are inside the schedule, otherwise you are not.

#2 - use a specific timestamp as reference of day - preferably a Monday. Then use the days function to get the number of days difference between your day and the reference, then use a modulo 7 ( value % 7) operator that allows you to get the offset of the day. For the time of the day, you need to parse the time using the format function and extract the hour part.

Thanks, Brindusa, this is an intriguing idea that I might explore. Currently, the client is ok with simply providing help text to guide the user that they should only enter a date within a particular hours of operation, but I'll keep this in mind if they find users are not following instruction.

I think it will still be great if in the future there is an ability to control the date picker with rules, maybe I will submit an idea.
