Usually no, as it is most common for machines to keep track of time using UTC and apply adjustments to display in local time according to OS-specific configuration rules.

For most OS's this change just means that you need to update the conversion rules from UTC to local time. On Unix and Unix-derived systems this normally involves updating a file in /etc (which sets the default timezone for the machine) and possibly a directory which has all the conversion rules for the world (e.g. /usr/share/zoneinfo). When updating the OS do not forget to update any chroot areas as well if you are running BIND in a chrooted environment. See your OS's documentation for more details.

The local timezone conversion rules can also be done on a individual basis by setting the TZ environment variable appropriately. See your OS's documentation for more details.
