** Class: RCTime (ref: prtime.h)
**
** RCTimes are objects that are intended to be used to represent calendar
** times. They maintain units internally as microseconds since the defined
** epoch (midnight, January 1, 1970, GMT). Conversions to and from external
** formats (PRExplodedTime) are available.
**
** In general, NCTimes possess normal algebretic capabilities.
