Sometimes it is very useful to handle time in milliseconds. I think it would be handy to have milliseconds in Time class. A lot of operations are executed in 0.5-2 seconds, and it is vital to see something more than 0 or 1 as a result.
What do you think?
I do not know. If I need subsecond times, I usually use int or double.
The whole purpose of Time or Date IMO is that they are not decimal. Once you have time as double, you can always convert to Time quite easily.
