Hitchhiker's Guide to Openbsd

8.25 - Why is my clock off by several hours?
By default, OpenBSD assumes your hardware clock is set to UTC (Universal Coordinated Time) rather 
than local time, assumed by some other operating systems, which can cause problems when 
multi-
booting
. 
Many other operating systems, can be configured to do the same, which avoids this problem altogether. 
If having the hardware clock set to UTC is a problem, you can change the default behavior of OpenBSD 
using 
config(8)
. For example, to configure OpenBSD to use a hardware clock set to US/Eastern (5 hours 
behind UTC, so 300 minutes): 
# config -ef /bsd
OpenBSD 4.9 (GENERIC) #671: Wed Mar 2 07:09:00 MST 2011
[e-mail]:/usr/src/sys/arch/i386/compile/
GENERIC
Enter 'help' for information
ukc> timezone 300
timezone = 300, dst = 0
ukc> quit
Saving modified kernel.
See 
options(4)
 and search for option "TIMEZONE=value" for more information.

8 - General Questions
Normally, the time zone is set during install. If you have need to change the time zone, you can create a 
new symbolic link to the appropriate time zone file in 
/usr/share/zoneinfo
. For example, to set 
the machine to use EST5EDT as the new local time zone: 
# ln -fs /usr/share/zoneinfo/EST5EDT /etc/localtime
