Description
Convenience wrappers to create date-times from numeric representations.
Usage
ISOdatetime(year, month, day, hour, min, sec, tz = "")
ISOdate(year, month, day, hour = 12, min = 0, sec = 0, tz = "GMT")
Arguments
year, month, day |
numerical values to specify a day. |
hour, min, sec |
numerical values for a time within a day. Fractional seconds are allowed. |
tz |
a time zone specification to be used for the conversion.
|
Details
ISOdatetime and ISOdate are convenience wrappers for
strptime that differ only in their defaults and that
ISOdate sets UTC as the time zone. For dates without times it
would normally be better to use the "Date" class.
The main arguments will be recycled using the usual recycling rules.
Because these make use of strptime, only years in the
range 0:9999 are accepted.
Value
An object of class "POSIXct".
