How do you measure time on a tide locked planet?

[QUOTE="Hornbein, post: 6833262, member: 489043"] If they live within reach of the dark side they might be able to see the stars. That makes a unit of a year. A Stonehenge can give you month by observing the appearance of certain stars and measuring their height above the horizon. The week could be determined by the moon. You can measure hours by water draining, by burning a standard unit, and so forth. You could have a big cistern that takes a week to drain. How [I]do[/I] you tell how old someone is (and thus when they reach maturity)? If they are like humans they grow a beard or menstruate, become lustful, etc. I live on an island where until recently older people did not know their age. The importance of this is the modern custom of arbitrary ages for retirement, voting, drinking, insurance, etc. Maybe animals have a sleep cycle, maybe they don't. Not helpful, I know. [/QUOTE]
