Subject: [PATCH] *lib/getdate.y: Factorize duplicate code for relative time
offset and hhmmss times.
I'm looking at this factorization-only patch, now.
Here are the changes I'm merging with yours:
- add a ChangeLog entry
- don't add trailing blanks
- don't add lines longer than 80
- adjust indentation and formatting to match existing style
- renamed the new functions

+ Use them in place of open-coded actions.
