This is a little off topic as it has to do with pure python (or VB).
Using the python parser you can get the current time with the function:
datetime.datetime.now().strftime('%H:%M') # use '%h:%M' for 12 hour time
Have a read of strftime behavior, note that this will be a string, not a datetime, so can only be stored in a string field.
The following python code can be run in a field calculate:
t = datetime.datetime.now() h = t.hour m = t.minute s = str(h) + ":" + str(m)
You would then return the string
s which would be something "23:51".
You should also explore the tool Convert Time Field which already exists and can extract out a variety of formatted date/times. It is in the same toolbox as the Calculate Field tool...
