>>>My problem is that, since I ignore seconds, the minute between 23:59:00 and 23:59:59 is "not accounted" for. The data set by VFP is used by the .NET application: compares the current time with the time set by VFP. So, the .NET application could be reading the current time as 23:59:30 and the logic will tell the problem that this is outside of the day hours/minutes (00:00 to 23:59). But as I type this, I am thinking of the following "solution" When converting the time set by VFP (e.g. 23:59) in the .NET application, I could add the seconds part of 59 (automatically). Therefore, the entire range of time will be accounted.

>>Of course the next question you may need to ask -- to what day does midnight belong? The 00:00:00 notation would suggest that midnight is the beginning of a day, whereas the 24:00:00 notation would suggest it is the end of a day.

In doing so, you've also avoided related "can of worms":
* where does noon belong? is it the end of the first half of the day, or beginning of the latter half?
* question of the beginning of a time period and the end -- 24:00:00 notation would suggest that first hour of the day would be 00:00:01 to 01:00:00 inclusive.
