UNIX for Dummies Questions & Answers

Hi,
I'm administrating a pretty old solaris (2.6) system. In the cronjobs I found that every night 2 o'clock a cronjob starts /usr/sbin/rtc -c. I've never seen this app in my life before so I looked at the manpage and it told rtc is for syncing Dos and Unix Systems. Did I understand it correctly?

Is there any need today to let rtc run? What's up with the system clock on solaris systems? I'm wondering if I can remove this cronjob.

Any help would be great

cheers

You might want to read Real-time clock - Wikipedia, the free encyclopedia and this: SunOS man pages

The latter document states that "-c" "checks for DST and makes corrections if necessary. It is normally run once a day by a cron job." I presume that if you are in a timezone with a daylight savings time you will need it.

I hope this helps.

Well are you sure with this? Because this sunnday the clocks are changing in my country but I think rtc does nothing if the manpage is correct because there's no /etc/rtc_config file on my system?
