Constructor Function for timeDate Objects


Constructs a timeDate object from a character vector, a vector of julian days, or a vector of milliseconds, or constructs an empty timeDate object.


timeDate(charvec, in.format, 
         format, zone, 
         julian, ms, in.origin=c(month=1, day=1, year=1960))


One of charvec, julian, or ms must be supplied, unless the function is called with no arguments.
charvec a character vector to read the times from.
in.format the input format string for charvec. The default value is timeDateOptions("time.in.format"). (Click class.timeDate in the SEE ALSO section for the list of allowable input format strings.
format the output format stored in the result. The default is timeDateOptions("time.out.format").
zone the time zone stored in the result. The default value is timeDateOptions("time.zone").
julian an integer vector of the number of days since in.origin. If ms is missing, this argument can also be a numeric whose fractional part gives the fraction of the day.
ms an integer vector of milliseconds since midnight.
in.origin the origin for the julian argument. This should be a vector with month, day, and year components.


Leap seconds do not cause NA values, but it can cause times of day to be off by a second on the days that contain them.
For information about possible values for the in.format and format arguments, see the documentation for the timeDate class (class.timeDate).
returns a timeDate object derived from the inputs.
