Well you are kinda straw manning me, considering my own words were "that's a problem" and not "don't deserve a title senior engineer". I also specifically said "senior dev" and not "senior engineer", which are very different things. Maybe re-read the comment chain with fresh eyes, since you seem to have taken a very antagonistic interpretation?

I think most people here can agree that seniors should be aware of standards for recording time. If you know you should write a date as "yyyy-MM-dd hh:mm:ss" (add precision or timezone information as required) then congratulations you are aware of the necessary standards.
