Daylight Savings Time

This morning I began the semi-annual ritual of resetting my clocks. “Spring forward” and all that.

I actually love the onset of Daylight Savings Time. By virtue of my work schedule, it is much better for me to have more daylight at the end of the day than at the beginning. I hate getting home when it is dark, since it really limits my options if there is something I want or need to do outside.

But it got me to thinking about the idea of time in space — or during space travel. Star Trek was all about the “Star Date” — which, one assumes, is synchronized across the cosmos to something. Obviously, things get sticky when you start factoring in travel close to the speed of light. Alastair Reynolds has done a good job of describing time, both relative to a planet “local Resurgam time” and the nature of time for those who spent a lot of — ahem — time in “Reefersleep.”

At any rate, I am intrigued by the idea of time relative to where you are in space and where you are trying to correlate the current time at a given location. Do you always keep your clocks synchronized with earth? Or is the there a cosmic analogue to the idea of an Earth Day?

One thing’s for sure: there isn’t any Daylight Savings Time in space.
