When I'm writing fantasy I try very hard not to use time defining or measuring words that we commonly use in conversation. Inch, year, mile, etc. are the types of words that I try to do away with. Minute and second are tricky ones, because they are small units of time that we reference frequently. I generally try to use moment instead of minute (not quite the same, but you didn't really mean a minute as 60 seconds in your example anyway), and instant instead of second. For measurements I generally go with body comparisons: hand, foot, pace. I would say if you think about it you can come up with something reasonable to use instead that most people will understand immediately.
What I try very hard not to do is make up words. I think it gets confusing when writers make up strange words to describe ideas we already have words for. Scifi is particularly bad at this. Farscape made up different words for every time interval and every time I hear them I cringe a little bit.
