Is there a way to compare two Java war files

Question

We created some war files for our web server some time ago and now rebuilt them.

To make sure that nothing has changed (and as a quality check), we tried to compare them using WinMerge. The differences we can see look as if they are associated with some metadata, for example. files created on different dates?

The difference in the lines seems consistent, for example.

"d} <

and

³Ze <

Military files are still the same size.

Is there a way to compare them that removes metadata like date?
