Finally, I figured out the issue! In order to store a time() from epoch,
your db type cannot be 'time' but instead must be 'float'
The crud.create form I was generating let the erroneous value thru, and the
db wasn't liking it; however, the form within appadmin caught the issue
saying it needed hh:mm:ss. I imagine what happened was I set the default
value for the field to time() and the type to 'time' and it tried to unpack
a datetime.time from the float only finding 2 values (left & right of
decimal). In my prior post, the default value was 0, hence need more than 1
value to unpack. not sure this is relevant to the originally posted
problem, but hopefully it'll help someone in the future.
what a noob...
