How do I subtract the value of a variable from another variable

[lostbit59]

I have a script that needs to save a file using a short time stamp in minuets. So before my loop I have

a piece of code that get the time called starttime. Later inside the loop I again get the time called ctime 

so how do I subtract the value of starttime and ctime?

Also less important, I tried to use Msgbox to display the value of the starttime, does not work

any pointers on how to best do this would be helpful.

Hi,

There are no pointers in the autoit syntax, all the pointers etc are internally handled.

The syntax is the following:

Msgbox(4096, $starttime, 6)

Please read the helpfile next time

In almost all the helpfile examples you have variables with message boxes.
