Summary

Impact

• agoAndDateBothSources shows relative and absolute date plus the corresponding author/committer relative date when they differ
• Updates default tooltip and status bar formats to use these new tokens

Validation

• Verify new date format tokens work in custom format strings
• Verify default tooltip and status bar formats show improved date information
• Verify agoAndDateBothSources correctly shows committer date when it differs from author date

Risk
