make_datetime

Efficient creation of date-times from numeric representations

Description

make_datetime() is a very fast drop-in replacement for base::ISOdate() and base::ISOdatetime(). make_date() produces objects of class Date.

Usage

make_datetime(
  year = 1970L,
  month = 1L,
  day = 1L,
  hour = 0L,
  min = 0L,
  sec = 0,
  tz = "UTC"
)

make_date(year = 1970L, month = 1L, day = 1L)

Arguments

`year`	numeric year
`month`	numeric month
`day`	numeric day
`hour`	numeric hour
`min`	numeric minute
`sec`	numeric second
`tz`	time zone. Defaults to UTC.

Details

Input vectors are silently recycled. All inputs except sec are silently converted to integer vectors; sec can be either integer or double.

Examples

make_datetime(year = 1999, month = 12, day = 22, sec = 10)
make_datetime(year = 1999, month = 12, day = 22, sec = c(10, 11))
