A new version of the chron add-on package is now available from CRAN. The previous version introduced code to ensure that chron would work correctly in the 21st century. Of course, the main issue is how to deal with 2-digit dates. To this end, the original author of chron, David James, indicated that the `y' format specifier was always meant to specify the year without the century (i.e., the year modulo 100), as in strftime(3)'s `%y'. Hence, there should be an error when using a number outside the [0, 99] range, such as 1999 or 2000, with the `y' format specifier. Several users have expressed their dislike of the new behavior and that using `y' with 4-digit years used to work, sort of. Hence, the new versions has changed the default behavior as follows. 2-digit years are expanded using 30 as century cutoff, i.e. 00 -> 29 21st century 30 -> 99 20th century All other values are left alone. In the next version, I want to introduce strftime(3) formatting specs, similar to the new timeDate class in S-PLUS 5. Most likely, ISO 8601 format (yyyy-mm-dd hh:mm:ss) will be used as default. -kh -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-announce mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
