 // MK's Javascript Clock Version 2, March 12, 2000

 // This piece of js code should give the Central European time anywhere on Earth
 // To adapt to another time zone adjust the value of variable tz,
 //   and modify the daylight/standard time switching if necessary
 //   (see e.g. my CST/CDT clock).
