Despite many people referring to a 'Date/Time Picker,' I have never actually seen this creature, and the referred to ActiveX Control is actually a Calendar, i.e. a Date Picker. But here is a thread from another Access forum where an old Access hand by the name of Brent Spaulding has posted a custom Time Picker. Note that I've never used it myself, but have had the link archived in case I needed it:
Access Help and How-to - Microsoft Office Time Picker; Date Picker; Date Time Picker - UtterAccess Discussion Forums
You might post back here and let us know how it works out for you.
Hope this helps!
The problem with making anything foolproof...is that fools are so darn ingenious!
