When printing make date-time tzones more clear

[hadley]

library(tibble)
base_time <- function(tz = "") {
  as.POSIXct(strptime("2015-06-01", "%Y-%m-%d", tz = tz))
}

tibble(
  time1 = base_time() + 3600,
  time2 = base_time("UTC") + 3600,
  time3 = base_time("Australia/Lord_Howe") + 3600
)
#> # A tibble: 1 × 3
#>                 time1               time2               time3
#>                <dttm>              <dttm>              <dttm>
#> 1 2015-06-01 01:00:00 2015-06-01 01:00:00 2015-06-01 01:00:00

Those are actually three different times, but you can't easily tell.

Not sure how to best display this information.

Time zone is the same for all items in a column, could go to the header:

#> # A tibble: 1 × 3
#>                 time1               time2               time3
#>                <dttm>           <dttm-02>           <dttm+11>
#> 1 2015-06-01 01:00:00 2015-06-01 01:00:00 2015-06-01 01:00:00

See #117 for a related discussion for list columns where all elements have the same type.

They are constant within a column, but can be quite long (e.g. "America/Argentina/ComodRivadavia").

That's why I'm suggesting to use the non-DST hour offset, would that be easy to obtain?

Closing in favor of the colformat issue.
