Filtering procmon results on time-of-day does not work as one would expect. Suppose the results show a line with time-of-day "7:44:26.4065994 AM".
- If you filter on 'Time of Day' begins with '7:44:26', all results are filtered out.
- If you filter on 'Time of Day' contains '7:44:26', you get the expected results.
- If you try to filter more precisely, specifying contains '7:44:26.40', all the results are filtered out.
Unlike the other procmon fields, which are uniformly treated as strings, the time-of-day field is not, apparently. There may be some way to filter precisely, but it's not obvious.
