Time values

Before I buy another video editing program I have a question.

I imported some video into Win Movie Maker.  

Time is displayed as HH:MM:SS.DD where HH is hours, MM is minutes, SS is integer seconds, and DD is decimal seconds.
There are 60 minutes in an hour, 60 seconds in a minute, and 100 decimal seconds in one second.

Movie Maker doesn't display 100 decimal seconds before changing the second value. It displays 20 decimal seconds before changing the second value.

When the decimal seconds increments from .19 seconds to .20 seconds the seconds value changes.
For example
00:00:20.17
00:00:20.18
00:00:20.19
00:00:21.00 Notice the change from 20 seconds to 21 seconds
00:00:21.01

Instead of a true counting of hundredths of seconds from .01 through .99 like this:
00:00:20.17
00:00:20.18
00:00:20.19
00:00:20.20 Didn't change from 20 to 21 seconds
00:00:20.21

The seconds change when the hundredths of seconds goes above .19. It's as though that while it is displaying .01 through .19 seconds it is actually .05 through .95 seconds.

Do the Adobe video editing programs accurately display decimal seconds?
