@mgorny could you please rebase? |
I can. But since you've already merged |

Hey @mgorny sorry for the delays and merge/rebase mess. I would appreciate a rebase (I won't interfere this time 🙈). |

Fix the `pendulum.tz.available_timezones()` to use `available_timezones()` function instead of iterating over the files in `tzdata` package. This is more in line with PEP 615, as the system timezone functions will operate on system-provided tzdata when available, and use the `tzdata` package only if it's not available. Therefore, the previous code would yield a potentially different list of timezones than the system actually provides. Furthermore, Gentoo provides a dummy `tzdata` package that does not provide any data, since Python always uses system tzdata. This change is necessary to make pendulum work again on Gentoo. Fixes python-pendulum#769
