from_datetimeoffset {datetimeoffset}

Convert to other datetime objects

Description

We register S3 methods to convert datetimeoffset() objects to other R datetime objects:

Usage

## S3 method for class 'datetimeoffset'
as.Date(x, ...)

## S3 method for class 'datetimeoffset'
as.POSIXct(x, tz = mode_tz(x), ..., fill = "")

## S3 method for class 'datetimeoffset'
as_date_time(x, zone = mode_tz(x), ..., fill = NA_character_)

## S3 method for class 'datetimeoffset'
as.POSIXlt(x, tz = mode_tz(x), ..., fill = "")

## S3 method for class 'datetimeoffset'
as_year_quarter_day(x, ..., start = NULL)

## S3 method for class 'datetimeoffset'
as_zoned_time(
  x,
  zone = mode_tz(x),
  ...,
  ambiguous = "error",
  nonexistent = "error",
  fill = NA_character_
)

Arguments

x

A datetimeoffset() object

...

Ignored

tz, zone

What time zone to assume

fill

If timezone and UTC offset info is missing what timezone to assume. See fill_tz().

start

The month to start the fiscal year in. See clock::as_year_quarter_day().

ambiguous

What to do when the "clock time" in the new time zone is ambiguous. See clock::as_zoned_time.clock_naive_time().

nonexistent

What to do when the "clock time" in the new time zone doesn't exist. See clock::as_zoned_time.clock_naive_time().

Details

We register S3 methods for the following:

• as.Date() and clock::as_date() returns the "local" date as a base::Date() object

• as.POSIXct() and clock::as_date_time() returns the "local" datetime as a base::POSIXct() object

• as.POSIXlt() returns the "local" datetime as a base::POSIXlt() object

• nanotime::as.nanotime() returns the "global" datetime as a nanotime::nanotime() object

• parttime::as.parttime() returns the "local" datetime as a parttime::parttime() object

• clock::as_year_month_day() returns a clock::year_month_day() calendar

• clock::as_year_month_weekday() returns a clock::year_month_weekday() calendar

• clock::as_iso_year_week_day() returns a clock::iso_year_week_day() calendar

• clock::as_year_quarter_day() returns a clock::year_quarter_day() calendar

• clock::as_year_day() returns a clock::year_day() calendar

• clock::as_naive_time() returns a "clock" naive-time

• clock::as_sys_time() returns a "clock" sys-time

• clock::as_zoned_time() returns a "clock" zoned-time

• clock::as_weekday() returns a clock::weekday() object

Value

A datetime object vector

Examples

  # {base}
  today <- as_datetimeoffset(Sys.Date())
  now <- as_datetimeoffset(Sys.time())

  as.Date(today)
  as.Date(now)
  as.POSIXct(now)
  as.POSIXlt(now)

  # {clock}
  clock::as_date(today)
  clock::as_date_time(now)

  clock::as_year_month_day(now)
  clock::as_year_month_weekday(now)
  clock::as_iso_year_week_day(now)
  clock::as_year_quarter_day(now)
  clock::as_year_day(now)

  clock::as_naive_time(now)
  clock::as_sys_time(now)
  clock::as_zoned_time(now)

  clock::as_weekday(now)

  if (requireNamespace("nanotime")) {
    nanotime::as.nanotime(now)
  }

  if (requireNamespace("parttime")) {
    parttime::as.parttime(now)
  }
