[bitfolk] Changing system time from UTC to GMT?

Hi all,

I am a recent newcomer to Bitfolk, and indeed VPS's in general, and so far
good - far surpassing expectations in fact.

I have been busy migrating several of my services from my home server to
the new VPS and have noticed a slight difference in representation in time
- the use of UTC versus GMT - in areas such as logs, application variables
(Apache date-related SSI's for example).

My question is, can I change the system clock from UTC to GMT and, if so,
how? I am aware that I could tweak most applications (e.g. Apache's config
timefmt command) however I would prefer to change this in only one place
if at all possible.

If this is doable, would I risk breaking anything? I've seen some mention
of time synchronisation issues between the VPS and host system in previous
discussions and so am conscious that this could be a dangerous area for
idle tweaking.

My preference for GMT/BST is largely aesthetic, and perhaps also simply
what I'm used to, with a slight hint of British tradition thrown in also!

Would be grateful for any advice.

Regards,

Mathew
