[Issues] datetime vs. DateTime

[Johannes Koppenhoefer]

Hi all, 

I found the DATE_OBS value of my RawBiasFrames to be of some strange type:

awe> rb = ( RawBiasFrame.instrument.name == 'WFI' )[0]
awe> type( rb.DATE_OBS )
<type 'datetime.datetime'>


in the past it was of type 

<type 'DateTime'>

Has something changed or is there a problem with the database? 
What is the difference between datetime.datetime and DateTime?

Cheers,
Johannes
