Re: Time

[Tom Droege <tdroege@veriomail.com>]

OK, I am patiently waiting for someone else to write the real time control 
program.  I write the date of the evening I start observing in the log book 
and on the data disk.  So anyone who knows what they are doing should be 
able to straighten it out.  I have been setting the time to within a second.

Other than that, I have decided not to solve this problem.  I have absolute 
confidence that I will never get this right.  Well, never say never, by 
extreme luck I might get it right on occasion.
