You misunderstand what Unix Time is. It's the number of seconds since 1970-01-01T00:00+00:00. It's always relative to UTC. And the number of seconds since epoch is always the same regardless of where you are on Earth.
As I write this it's
1702600950for you, for me, and in Sydney. Timezones (and DST, and leap seconds, and other political fuckery) only play a role once you want to convert1702600950into a "human" datetime. It corresponds to2023-12-15 00:46:02 UTCand2023-12-14 16:46:02 PST(and the only sane and reliable way to do the conversion is to use a library which depends on the tzdata).
