We might not, depending on various things. If you live on a planet with a very short or long year, its year may be of little convenient use to you. If your friends come from various planets, you deal with years of different lengths, so having to specify which year you mean, or use a standard one which doesn't agree with any of yours, may be inconvenient. You may not live on a planet at all, but instead reside permanently on a ship, or in a system with only planetoid belts, or whatever.
Some science fiction works have used metric seconds, instead. (
The Outcasts of Heaven Belt by Joan D. Vinge, for example.) "I'll be done in a kilosecond" or a megasecond-long vacation. My brother had a party when he hit a gigasecond.
