I don't know of a way, but it seems Logstash can be told how to do the
right thing:

https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html#plugins-filters-date-locale

See match and:

http://joda-time.sourceforge.net/apidocs/org/joda/time/format/DateTimeFormat.html

z       time zone                    text          Pacific Standard
Time; PST
