Take a look at the clock when you sync up. It doesn't jump suddenly, unless maybe it's way off. In some cases anyway, the system appears to try adjusting it smoothly. It may take a while for it to get to the "correct" time. You'll be much better off checking with a real reference. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
