Hi Rich,
It is suppose to be NOW() when u select today on a date/time type of field.
I’m on Skuid V8.13 and it works fine.
Looking in releases I see the latest release has a note that this issue has been fixed
Rockaway Point Release - Iteration 10: [SKUID-2387] - “TODAY” resolves to midnight instead of Current Time
If not on latest version, please update and it should work
