Fractional DateTimeField values

The fractional part of a datetime object seems to be always truncated. Looking through the code a bit, I also see that it doesn’t expect there to be one: https://github.com/coleifer/peewee/blob/master/peewee.py#L204

I assume this is primarily cause not all databases support fractional seconds (older versions of MySQL, for instance). Is there a way to optionally support it if the database underneath supports it?

After read the information you provided, I got this, and it seems work:

database = MySQLDatabase(dbname, fields={'datetime_fsp6': 'DATETIME(6)'})

class DateTimeFsp6Field(DateTimeField):
    db_field = 'datetime_fsp6'

class FooModel(Model):
    ctime = DateTimeFsp6Field(default=datetime.datetime.now)

@luisulloa IIUC, not all MySql versions support this
