Crossing midnight at the end of the year.

14dec05

 Background:

  The data taking uses irig from the trak clock to keep track of time. The irig standard does not include the year with the information that it distributes. To get around this, the datataking stores the year information  in the file:
/home/online/vw/etc/initDat/year
This is an ascii file with the first line containing the current year as a 4 digit number (eg. 2006).

    This file is read by the pointing program and the irigServ program when they are started. Both of these programs are running on the vme pointing crate.
