ACWST time now (Australian Central Western Standard Time)

What ACWST means

ACWST stands for Australian Central Western Standard Time, UTC+8:45. It is used in Eucla and the Eyre Highway strip on the Western Australia–South Australia border.

It is a standard (winter) time. Places on ACWST that observe daylight saving time switch to ACWDT (UTC+9:45) in summer, so ACWST is a fixed offset while the local clock is not.

tzdata, the database behind phones and computers, does not use the letters ACWST: it writes UTC+8:45 for this time. ACWST is the customary or CLDR name, so software may show “UTC+8:45” or “GMT+8:45” instead.

Where and when ACWST is used

1 zone uses ACWST all year. Computed from tzdata under the current rules (tzdata writes UTC+8:45; the list follows the CLDR name).

ACWST converted to other zones

Every column is a fixed offset, so this table is valid on any date. Remember that the regions behind some columns switch to summer time (EST to EDT, CET to CEST, GMT to BST); the clock in those cities is then an hour later than the column.
