dt <- datetime_at_tz(dt0, "America/New_York")
print(dt)
dt <- datetime_at_tz(as.POSIXct(dt0), "America/New_York")
print(dt)
dt <- datetime_at_tz(clock::as_zoned_time(dt0), "America/New_York")
print(dt)
# Can also use `lubridate::with_tz()`
if (requireNamespace("lubridate")) {
dt <- lubridate::with_tz(dt0, "America/New_York")
