A quick google search seems to get me nowhere. What are valid time zones in lubridate\'s tz option? In particular, am looking for Brasilia\'s time zone. Thanks!
tz
Take a search through OlsonNames() which provides a list of all the valid timezones on the host system. e.g.:
OlsonNames()
grep("Brazil", OlsonNames(), value=TRUE)
...provides four possible results for Brazil.
