If you think like that then timezones must seem like an inconvenience as well. And don't get me started on the daylight savings time.

You are right, it's not. From what I have seen the preferred term is light-year, but this was not the best way to express this. I'll try another way:
google "site:nasa.gov parsec" 6,570 results
google "site:nasa.gov light-year -buzz" 42,000 results (the "-buzz" is to exclude Buzz Lightyear from the results)
Springerlink.com is a website where you can find scientific journals.
google "site:springerlink.com parsec" 1,820 results
google "site:springerlink.com light-year" 595,000 results
What makes you think that parsec is used more than lightyear in reality?

And yet people seem to have agreed that using the seasons (and therefore the year) is a better way to tell the passage of time.
