Subtracting minutes from ToTime Integer

[nicbizz]

Hi,

I have sometime like this in my code:

int startTime = 93000
int endTime = 155000

if (ToTime(Time[0])<startTime || ToTime(Time[0])>endTime - [minutes])
   stopEntry = true;

The [minutes] part is where I'm having issues with. How can code it so that I can specify the number of minutes to subtract from endTime? If I'd like it to end 50 minutes before endTime, simply coding

endTime - 5000

does not really work in all situations (i.e. if endTime was 160000, then 160000 - 5000 would be 155000, or 3:50pm instead of 3:10pm).

Any help would be much appreciated. Thanks.

Update:

This is what I managed to knock out:

myDateTime = DateTime.ParseExact(endTime.ToString(), "HHmmss", CultureInfo.InvariantCulture);
myDateTime = myDateTime.AddMinutes(-20);
				
string format = myDateTime.ToString("HHmmss");
int endTimeFinal = Int32.Parse(format);

It's brutal. It's ugly. It's probably a lot longer than it needs to be. But it works.

Any suggestions on how I can "elegant-ize" it?

Thanks!

Update #2:

Ahh, the wonders of stackoverflow.

Replaced:

string format = myDateTime.ToString("HHmmss");
int endTimeFinal = Int32.Parse(format);

with

int endTimeFinal = int.Parse(myDateTime.ToString("HHmmss"));

So far, so good!

You evidently know how to code with DataTime objects. Why not just use them directly? After all, Time[n] objects are already DateTime objects.

Not to put a fine point on it, but that is far more elegant than all this trying to pretend "times" are integer objects.
