yyyymmdd2Int(x)

yyyymmdd_HHMMSS_UTC(x)

Arguments

x	A character vector, represeting a date in dd/mm/YYYY format (ddmmyyyy2Int) or YYYY-mm-dd format (yyyymmdd2Int), or a date time (for yyyymmdd_HHMMSS_UTC).

Value

Missing values are mapped to NA_integer_ as would be expected, but so too are dates not in the above format, including for example 1/2/2000 (no leading zeroes).

yyyymmdd_HHMMSS_UTC("2021-05-05 00:55:55")
