GMT is never corrected with an odd one second correction (because being
solar time in Greenwich would require figuring out a way of shifting the
earth's rotation by the required 15 seconds of arc to match). It is UTC
that gets the 1 second corrections. The time that we use in winter,
although frequently (and incorrectly) referred to as GMT is in fact UTC.
But as I said: for nearly all practical purposes, they are the same thing.

It is UTC+1. Strictly, it is *not* GMT+1, though frequently stated as such.
