I was reading up on NTP, and I've come across this:
"Some areas, such as most of North America and Europe, have consistent and common rules for when to switch between winter or Standard time and summer or Daylight Saving Time. The traditional North American rule, and the default for Cisco routers when they are configured for summer time, is to move an hour ahead at 2:00 AM on the first Sunday in April, and back an hour at 2:00 AM on the last Sunday in October."
As here in Europe the summer time begins the last week of March and ends last Weekend of October, I was wondering:
Is it enough to point the device to an NTP server specifying on this the right time zone, or do I also have to manally set the summertime period e.g.:
Router(config)#clock summer-time BST recurring last sun mar 01:00 last sun oct 01:00
Thanks to read
NTP is always used as a reference clock and not as a local clock, as the NTP server just points the 'correct time' and we need to specify our 'local time' and DST settings, so that even in the case of a router reboot or link failure the router can cross check its own time with a reference clock and adjust the local time accordingly.
