Ignoring date column in beyond compare file comparison

I'm using BeyondCompare3 i've two files with lines containing with this kind of format.


I want to omit the date from the comparison.

I've selected Session > Session Settings > Importance Tab > Edit Grammar button and created a new rule.

After entering an Element name, I've selected Category of Basic, checked Regular Expression and searching for Text. [0-9]{1,2}:[0-9]{1,2}:[0-9]{1,2}.[0-9]{1,3}. I've also tried /[0-9]{1,2}:[0-9]{1,2}:[0-9]{1,2}.[0-9]{1,3}/.

I then click 'ignore unimportant differences' on the tool bar.

I was hoping this would ignore the date column in the comparison. But it doesn't.

Any pointers on this or other tools/scripts would be very much appreciated.



In Beyond Compare 4.1.9, you can ignore Modified Date by unchecking "Compare timestamps" in tab "Comparison" of the "Rules" window.

You can also add a regular expression to define text to be ignored (Unimportant text) in the Rules section like so:


In a 'Table Compare' session, comparing both files do the following:

  • Select rules, tab columns;

  • Edit the date column;

  • Check the unimportant checkbox;

  • Enable minor (to ignore minor and unimportant differences);

A date tolerance is also an option, but that is not your question.
