Calculating Time Differences between Two Machines

Written by Allen Wyatt (last updated December 31, 2022)
This tip applies to Excel 97, 2000, 2002, and 2003


Don has a computer that has access to several different servers over his office network. These servers do not have their clocks synchronized, and Don was wondering if there was a way, in VBA, to determine the time discrepancy between a given server and his machine.

In order to figure out the time discrepancy, you'll need to figure out two times—one on your machine and one on the server—and then compare them. Getting the time on your own machine is easy enough; just use the Time function in VBA. Getting the time on another machine is more difficult, as there is no built-in function that facilitates this task.

You can, however, use an API function call to determine the time on a remote server. Exactly how you would develop such a function call is beyond the scope of this tip, but you can find a pretty good tutorial online for accomplishing the task:

Take a look at the page, and you can adapt the code to fit your needs. The fGetServerTime function returns a string that contains the complete date and time. You can then use the TimeValue function in your macro to convert this string into a native Excel time value. Once converted, you can compare the value to the internal system time to determine the discrepancy you need.
