ISOdatetime: Construct Date-time Objects¶

Description¶

ISOdate and ISOdatetime construct date-time objects from numeric representations. Sys.time returns current time.

Usage¶

ISOdatetime(
  year,
  month,
  day,
  hour,
  min,
  sec,
  tz = "",
  lenient = FALSE,
  locale = NULL
)

ISOdate(
  year,
  month,
  day,
  hour = 0L,
  min = 0L,
  sec = 0L,
  tz = "",
  lenient = FALSE,
  locale = NULL
)

Sys.time()

Arguments¶


`year`, `month`, `day`, `hour`, `min`, `sec`	numeric vectors
`tz`	`NULL` or `''` for the default time zone (see `stri_timezone_get`) or a single string with a timezone identifier, see `stri_timezone_list`
`lenient`	single logical value; should date/time parsing be lenient?
`locale`	`NULL` or `''` for the default locale (see `stri_locale_get`) or a single string with a locale identifier, see `stri_locale_list`

Value¶

These functions return an object of class POSIXxt, which extends upon POSIXct, strptime.

You might wish to consider calling as.Date on the result yielded by ISOdate.

No attributes are preserved (because they are too many).

Differences from Base R¶

Replacements for base ISOdatetime and ISOdate implemented with stri_datetime_create.

ISOdate does not treat dates as being at midnight by default [fixed here]

Examples¶

ISOdate(1970, 1, 1)
## [1] "1970-01-01T00:00:00+0100"
ISOdatetime(1970, 1, 1, 12, 0, 0)
## [1] "1970-01-01T12:00:00+0100"
