A place's offset when summer time is not in force — the baseline, not the exception.
Standard time is the offset a jurisdiction keeps outside any daylight saving period. It is the legislated baseline; summer time is the departure from it.
The distinction matters in contracts and schedules that name a time zone. An agreement specifying a deadline in a named standard time means something different in July from one that means local civil time, and the difference is an hour in exactly the season people are least likely to check.
Where a jurisdiction does not observe daylight saving, standard time and local civil time are the same thing all year, which is most of the world.
Standard time is the baseline. Daylight saving is the seasonal departure from it, and a place alternates between the two.
Local time is whatever the clock says now, which is standard time for part of the year and summer time for the rest.
