DST time change on Linux

[Ratzie]

We are currently running NTP, but we do have our Timezone set to:
[root@server sysconfig]# cat clock
ZONE="America/Winnipeg"
UTC=false
ARC=false
[root@server sysconfig]# date +%Z
CST

We will be changing to DST to following the american Daylight saving time.
Do we need to modify our server, even if we are using NTP?
What zone would we change to?

You can use the zdump -v America/Winnipeg command to identify when the DST changes will occur.

You can modify your time zone source file and compile with zic if you want to do some customizations to the file.
