Valid time zones in lubridate

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!

library(lubridate)
dts <- c("6-3-1995 12:01:01","29-3-1995 23:01:01","29-3-1995 20:01:01")
dmy_hms(dts)               # locale's tz default
dmy_hms(dts, tz = "chile") # Chilean time (has one time zone only)
Solution

  • Take a search through the OlsonNames() in the standard base R package, which provides a list of all the valid timezones on the host system. e.g.:

    grep("Brazil", OlsonNames(), value=TRUE)

    ...provides four possible results for Brazil.
