"It wasn't until I was past forty that it bacame clear that I was going to be quote, successful, unquote."
- Isaac Asimov

Local Time Clock  
  A clock for use in airships that always indicates the time for the place they are flying over.  

The officer laughed. "No, that clock never stops. It is a local time clock, indicating the local time at any spot on the surface of the earth over which we happen to be flying at the moment. Its speed is controlled by a compass and an earth speed indicator, all corrections being automatic. We are now traveling toward the west at about a thousand miles per hour, so we are, as it were, keeping up with local time. Hence the hands are stationary. Should we change our course the compass and speed indicator would keep the clock on the proper local time. For instance, if we were now flying due south or due north along a meridian where the local time is the same, the clock would run at normal speed. On the other hand, were we flying due east at the speed we are now traveling westward, the clock would run at double speed. Again, should we increase our present speed in the course we are now holding the clock would run backwards. This is a great factor in determining our exact position during inclement weather."

Published by Air Wonder Stories in 1929
