Besides my PC, are there other things I need to worry about on my computer network?


Q: Besides my PC, are there other things I need to worry about on my computer network? Are routers, telephone PBX generally affected by these daylight saving time changes?
A: Theoretically, any device that uses time specific information (especially if it shows a time in your local timezone) could be affected.   With many devices (such as VCRs), the only change will be you’ll do the manual change three weeks earlier than last year.  However, with more advanced devices (computers, as an example) that interact with OTHER devices and typically “know” to reset themselves – yes, they are affected, as without some sort of update they won’t know about the new date rules.  


Some devices also operate in “UTC” (Universal time) and don’t really “care” about Daylight savings times, so those aren’t really affected.   Best bet is to check with the manufacturer of any device you have concerns about.  


The good news is that is most cases of consumer type devices; worst case scenario is usually that the time on that device might be an hour off for a few weeks unless you manually change it.
