The R package 'timeDate' provides class 'timeDate' for working with date/time. The 'timeDate' class fulfils the conventions of the ISO 8601 standard as well as of the ANSI C and POSIX standards. Beyond these standards it provides the "Financial Center" concept which allows to handle data records collected in different time zones and mix them up to have always the proper time stamps with respect to your personal financial center, or alternatively to the GMT reference time. It can thus also handle time stamps from historical data records from the same time zone, even if the financial centers changed day light saving times at different calendar dates.

Class 'timeInterval', introduced in v4050.111, represents time-date intervals. Suitable metods are defined for manipulating them, including union, intersection, complement, set difference and other utilities.

Package timeDate is part of the Rmetrics suite of R packages and is developed on R-forge at timeDate. The root of Rmetrics is at R-forge.
