This change updates the vendored tzdata database to version 2017b (released 2017-03-20). The TestFirstZone test (which always uses the vendored database) is updated to make it work with the new timezones database. (The Tokelau abbreviation was changed from 'TKT' to the numeric abbreviation in tzdata-2017a) Fixes #19376 Change-Id: I0dea93e8703992de5c92c7840b8bacad9d02c50d Reviewed-on: https://go-review.googlesource.com/44832 Run-TryBot: Brad Fitzpatrick <bradfitz@golang.org> Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org>
