fix: 🐛 timezones abbreviations inconsistency/mismatch across timezones

[punkbit]

Why?

Found inconsistent timezone abbreviations across timezones, causing test failures, e.g. users in En-US get "EST", while EN-UK get "GMT-5".

For example, let's say we call:

formatTimezone(date, "America/New_York")

Where date is:

'Thu Jan 22 2026 13:25:56 GMT+0000 (Greenwich Mean Time)'

The following is expected:

"EST"

But someone based in London/UK would get:

"GMT-5"

How?

• Declares a default timezone for date formatter
• Split formatTimezone into date utils
• Creates a test/spec for date utils, formatTimezone

Preview?
