Hi,
I believe, in these cases, you can just test, whether there is a
non-integer part in the timestamp in seconds, which will be stored as
microseconds accordingly.
>>> 1092787200/1000.0
1092787.2
0.2 s is stored (and shown in repr(...)) as  200000  microseconds.

There are some peculiarities in handling date and time calculations
reliably as well as in the floating point math, but they don't seem to
be involved here.
