It depends on what is used to determine the time zone automatically, a
geolocation which can be ambiguous if you are close to some border, or
e.g. the telecommunication network used by your handheld.
Even the latter can be wrong.
For example, I've visited the Canary Islands located in the Atlantic, in
zone UTC+0, but these islands belong to Spain which is located in the
zone UTC+1, so my handheld selected UTC+1 automatically, and I had to
correct it manually to UTC+0 to have the real local time.
