This question already has an answer here:
I operate almost entirely in one time zone. Supposing a Data Center in another time zone, it would make sense to configure the machines in that data center to use my time zone, and not local.
Are there any drawbacks to this approach?
EDIT: My assumption is that all the devices use UTC and then the time zone configuration comes into play at some points when applications are presenting time information to humans, i.e. logging.
