Can I be sure ntp knows that my 2 hour time difference on the hardware clock is correct and not an error? Remember that the hardware clock is UTC time. And we do not all live in that timezone.
ntp doesn't care about timezones.
http://en.wikipedia.org/wiki/Network_Time_Protocol
"It provides Coordinated Universal Time (UTC). No information about time zones or daylight saving time is transmitted; this information is outside its scope and must be obtained separately."
If you think about it for a moment that *HAS* to be the case. Any particular reference site can be accessed from anywhere in the world - that is from any time zone.
The 'seperately' in teh case of Linux comes from _either_ consulting the TZ environment variable _or_ consulting /etc/timezone
The ntp protocol would be most sane if it were transmitted only as UTC. What a local system decides to do with that information is a whole different question - and one the ntp protocol really can't address. openSUSE seems to expect that the system clock is UTC, no matter what the battery clock is. Or this is how it looks to me.
