System neutral Daylight Savings Time response?
Perhaps you should be using the chron package. It has no time zones in the first place.

I'm searching for an r command that will notify me if I create a time that does not exist due to Daylight Savings Time. For example, if I run the following command on a windows machine
ISOdatetime(2010,03,14,2,10,0, tz = "") # My system time is set to the
United States Central Time Zone [1] NA R returns NA, which is the behavior I want. However, if I run the same command on a mac, R returns a POSIXct object and I have to examine the object manually to notice that I had tried to create an impossible time. ISOdatetime(2010,03,14,2,10,0, tz = "") [1] "2010-03-14 01:10:00 CST" Is there a method of creating time objects in R that will always return NA for non-existant times, no matter the operating system? Thank you sincerely, Garrett ? ? ? ?[[alternative HTML version deleted]]
