These functions return the properties of an instance of the
CFTime class. The properties are all read-only, but offsets can be added
using the + operator.
Value
calendar() and unit() return a character string.
origin() returns a data frame of timestamp elements with a single row
of data. timezone() returns the calendar time zone as a character
string. offsets() returns a vector of offsets or NULL if no offsets
have been set.
Functions
definition(): The definition string of theCFTimeinstance.calendar(): The calendar of theCFTimeinstance.unit(): The unit of theCFTimeinstance.origin(): The origin of theCFTimeinstance in timestamp elements.timezone(): The time zone of the calendar of theCFTimeinstance as a character string.offsets(): The offsets of theCFTimeinstance as a numeric vector.resolution(): The average separation between the offsets in theCFTimeinstance.
