Efficient creation of date-times from numeric representations

Source: R/instants.r

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

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)

#> [1] "1999-12-22 00:00:10 UTC"
make_datetime(year = 1999, month = 12, day = 22, sec = c(10, 11))

#> [1] "1999-12-22 00:00:10 UTC" "1999-12-22 00:00:11 UTC"
