Bug->Doc #78669 [Sus->Opn]: timezone_abbreviations_list only lists from compiled in db, not PECL timezonedb

Edit report at https://bugs.php.net/bug.php?id=78669&edit=1 ID: 78669 Updated by: derick@php.net Reported by: andy at asjohnson dot com Summary: timezone_abbreviations_list only lists from compiled in db, not PECL timezonedb -Status: Suspended +Status: Open -Type: Bug +Type: Documentation Problem Package: Date/time related Operating System: Linux PHP Version: 7.3.10 Block user comment: N Private report: N New Comment: I am going to mark this as a documentation issue. This function uses timelib's timelib_timezone_abbreviations_list which returns a precompiled list of timezone abbreviations for lookups for fallbacks. It is too computationally expensive to do compile this list at each call per PHP process (it takes seconds), and hence the list as returned by the PHP function uses this pre-generated list instead. I also generally frown upon using abbreviations for any input, as these are often not unique, and/or ambiguous. If you must have the latest version, then the best course of action is to use the latest PHP version, which will have the latest version of both the timelib library, rules, and this precompiled list.

Thanks.

Expected result: ---------------- Expected result is timezone_abbreviations_list from PECL timezonedb. Function timezone_identifiers_list works with PECL timezonedb as expected. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78669&edit=1
