# Abbreviations/synomyms to IANA timezone name map from
# https://en.wikipedia.org/wiki/List_of_time_zone_abbreviations.
#
# TimeZone abbreviations are not unique. We pick the ones most relevant to the
# Cloud SDK. For example, CST is used for US/Central, China standard time and
# Cuba Standard Time. Most service date/times will be UTC or have an explicit
# numeric +/-HH:MM timezone offset, so duplicates will not be a big problem.
