Timezone abbreviations vs IANA
National and everyday timezone names often differ from IANA IDs. This table pairs abbreviations and common names with the IANA zones they typically map to.
IANA IDs are matched via ICU English zone names, seasonal short abbreviations, UTC offsets, and curated overrides. Abbreviations without a real IANA zone (such as military letter codes or AoE) are omitted. One abbreviation can cover many IANA zones, and some labels are ambiguous across countries.
