GMT+8 resolves cleanly here, but Asian labels often share letters with American or European ones — IST is shared between India and Israel, for instance. Pinning Asia/Taipei avoids that whole class of confusion.
Asia/Taipei does not show an offset change in the next year, which makes GMT+8 predictable for short-term scheduling. Predictable is not the same as permanent — civil-time rules still get changed by governments on relatively short notice.
For precise work, the safest equivalent of GMT+8 is the exact IANA zone used by your city or system. Asia/Taipei sits at +08:00, ahead of UTC, which means daily logs in this zone reach a new calendar date before UTC does — a small detail that breaks date-based reporting if missed.
Even with one canonical meaning, GMT+8 spans 2 IANA zones — pin to Asia/Taipei when DST or historical-rule precision matters.
