RLPlot's internal storage of date- and time data is a floating point number representing days after 1-Jan-1900 starting with 1. The decimals give the fraction of the day. Thus the 5-Jan-2006 equals to 38721, and 5-Jan-2006 12:00:00 equals to 38721.5. Thus a time value alone is in the range 0.0 - 1.0, 12:00:00 equals to 0.5. The conversion between internal values and a human readable form is controlled by formats, text strings where each character stands for a specific conversion of the date- and time value. Characters not included inthe table below are either copied to the output or ignored during input.
