Please listen to @mj1856 saying "Lists like these are dangerous". You will soon have errors in your code, if using these hardcoded lists.

@kamleshwebtech you don't PHP much, do you?

var_export($america_timezones_list);

RESULT:

array (
  '+00:00' => '(+00:00) Danmarkshavn',
  '-01:00' => '(-01:00) Scoresbysund',
  '-02:00' => '(-02:00) Noronha',
  '-03:00' => '(-03:00) Argentina/Ushuaia',
  '-03:30' => '(-03:30) St Johns',
  '-04:00' => '(-04:00) Guadeloupe',
  '-05:00' => '(-05:00) Toronto',
  '-06:00' => '(-06:00) Monterrey',
  '-07:00' => '(-07:00) Boise',
  '-08:00' => '(-08:00) Whitehorse',
  '-09:00' => '(-09:00) Metlakatla',
  '-10:00' => '(-10:00) Adak',
)

You'd probably be better off by switching keys and values.

Warning! Please, do not use lists like this when trying to work correctly with time zones.

This is not a list of "All world timezones". It is not a complete list. It is not even time zones, just random values that may look like time zones, but are so far away from real time zones. Time zones can not be simplified to hardcoded lists like this.

Using lists similar to this for representing time zones will always fail.

Please read the important points in the comment from mattjohnsonpint (from 2017).

Yeah, @epursimuove is right, because eg (GMT -5:00) Eastern Time (US & Canada), Bogota, Lima is not true,
because Eastern Time in common has daylight saving time EST/EDT, but Bogota and Lima doesn't observe daylight time

echoing the "this list is wrong" comments
I'm in the UK, and we're not on GMT at the moment, GMT is 12:15 and it's currently 13:15, or BST, or UTC+1, or GMT+1 here. Daylight savings time in the UK started on the same date as "Most European countries", 31 March 2024.

As another example of why not to use a hardcoded or a simplified list...

Amsterdam is currently using CEST, or Central European Summer Time, or UTC+2 (Daylight savings started there on 31 March 2024). Right now, it the same time in Amsterdam, The Netherlands as in Harare, Zimbabwe, which currently observes Central Africa Time (CAT) all year. IST (Israel Standard Time) is also UTC+2, but not currently observed, because Israel is on Daylight Savings time (UTC+3, which started on 29 March 2024). Not to be confused with IST – Irish Standard Time (UTC+1) or IST – Indian Standard Time (UTC+5:30). Also note a lot of these place names aren't in the lists above (Amsterdam, Harare, Zimbabwe, Israel, Ireland, India).

if you're looking for actual timezones, try https://en.wikipedia.org/wiki/List_of_tz_database_time_zones which is based on the IANA standards

and for a shorter, more textual version https://www.timeanddate.com/time/current-number-time-zones.html (there's 38 for today, 25 April 2024)

I'm currently making a spreadsheet to help me get a time zone list for use with a summer events form, using different resources, and starting at the top (UTC +14), I've already found the following

Short description notes
TOST Tonga daylight savings (UTC +14) no longer in use since 2019
LINT UTC-10 Pacific Line Islands UTC +14 in use since 1994
NZDT New Zealand Daylight Time (UTC +13) used in NZ and Antarctica summers, from 29 Sep 2024. from Apr-Sep use NZST (UTC +12)
