About UTC−1
UTC−1 is 1 hour behind Coordinated Universal Time: when it is noon UTC, it is 11:00 AM at UTC−1.
1 zone keeps UTC−1 all year, covering 1 country or territories: Cabo Verde.
1 zone uses it only in winter and moves to UTC+0 in summer, for example Azores.
2 zones reach it only in summer, from standard time UTC−2, for example Nuuk and Scoresbysund. So the set of places on UTC−1 changes twice a year.
For a fixed offset in software, tzdata provides Etc/GMT+1; note the inverted sign of these POSIX-style names.

UTC−1 converted to other offsets
Fixed offsets only, so the table holds on any date; a city that observes daylight saving time is an hour later than its standard column in summer.
