One feature that is necessary for a some segments of the financial industry
is highly customized time formats.
The particular date/time formats I am seeking are (or something similar):
XXXXXXXX - milliseconds after midnight
XXXXXXXX.qqq - milliseconds after midnight point microsec
XXXXXXXX.wwww - milliseconds after midnight point 100 nanosecond units
YYYYYYYYYYY - usec after midnight
YYYYYYYYYYY.q - usec + 100 nanosecond units
NNNNNNNNNNN - nanoseconds after midnight (yes, last two would be 00 with Datetime)
Implmenting would be appreciated, and may help bring others from my segment to your product.
