Actually, the GPS-UTC offset is part of the almanac (see e.g. [1],
"word" 9, byte 1 of SubFrame 4). That's an important distinction to
make since 30 seconds are enough (in ideal conditions) to download the
whole ephemeris (for a given satellite) but obtaining full almanac
requires at least 12.5 minutes.
