Unfortunately, your workaround did not solve my problem fully. I successfully created the FracTime type which extends Time and that shows a field for fractional seconds. However, when I try to insert values into the FracTime column, I am still unable to to specify the fractional seconds part. Even after modifying Time's process method in lib/sqlalchemy/dialects/mysql/base.py to accept microseconds, I was still unable to get it to work.
To ensure that it was not a problem with sqlalchemy, I turned on logging to look at was being passed to the DBAPI. What I see is: ... INFO:sqlalchemy.engine.base.Engine.0x...a3d0:(4L, 7.48, 0.27, datetime.timedelta (0, 8, 26), 93, 0, 0, 62032, 0, 0, 19, 15573, 0) ... It looks like datetime.timedelta is holding the microseconds correctly (that is 0 minutes, 8 seconds and 26 microseconds). It looks to me that sqlalchemy is correctly passing the microsecond value onto the DBAPI. After your workaround, this seems to have confirmed that I am having a problem with my DBAPI's (which I think is MySQLdb) communication with the db. Please let me know if you have anymore ideas.
