When I run php artisan version:absorb
only updated

current:
  label: ''
  major: 1
  minor: 0
  patch: 5
  prerelease: 13-g89a88e67
  buildmetadata: ''
  commit: 89a88e
...

the timestamp part not updated

I don't want to use php artisan version:timestamp,because it updates the timestamp part in the now time,
I want to update time sync git commit simestamp

Am I missing something?
