For example, at 3:00 AM, the time falls back to 2:00 AM, repeating a full hour of times from 2:00 AM to 3:00 AM on the same date. By the RFC 5545, we cannot accommodate this case. All datetimes should be BEFORE the transition if ambiguous. However, dateutil can create a timezone that allows the event to be after this ambiguous time span, of course. Each event has its timezone saved in it. zX-TZNAMESUMMARYN)'issue_722_timezone_transition_ambiguityeventsstrstartrt) calendarsr>rcaleventexpected_tzname actual_tznames&&& r3test_dateutil_timezone_when_time_is_going_backwardsrsSEEC::c?E% +,OKK&&(M  +=U9-== +rc<V^8dQhR\R\R\/#)rqueryrreturn)rr)rs"rrrs!$$c$$S$rct\VRV/4p\T4# \dp\T4ThRp?ii;i)zThe tzid from the query.rN)eval Exception ValueErrorr )rrr{es&& r query_tzidrsC'eeS\* F ## 'Q&'s 7 27rcdVPp\W4pVP4pW49gQhR#)z*Add the missing timezones to the calendar.N)issue_722_missing_timezonesrget_missing_tzids)rrrr tzss&& r%test_add_missing_timezones_to_examplers199C e !D   !C ;;rcVPp\4p\F,p\W14p\ VRV4VP V4K. \ V4\ \48XgQhR#)zGWe make sure each query tests a unique place to find for the algorithm.z->N)rsetqueriesrr*addr)rrtzidsrr s& rtest_queries_yield_unique_tzidsr%sW  / /C EE%% eT4  $ u:W %% %rcVPpVPP4p\\ RV44pVP 4V8XgQR4h\ V4\ \48XgQR4hR#)z)Make sure all tzids are actually queried.zTZID=([a-zA-Z_/+-]+)z&We find all tzids and they are unique.zWe query all the tzids.N)rraw_icsr&rrget_used_tzidsrr)rrrawidss& r"test_we_do_not_miss_to_add_a_queryr0sj  / /C ++   C g,c2 3C    3 &P(PP & s8s7| #>%>> #rczVPpRVP49gQhRVP49gQhR#)z6If we have an unknown tzid with no timezone component.
