I'd put it on par with using a map and compass, in terms of importance. You might not die if you don't know it, but if you need to self extract, it's going to be really useful to know.

Although, working outside in the summer, I usually leave my watch inside and get time on the sun. I'm within 15 minutes most of the time, plus or minus.
