Hi. I frequently convert date and time data to and from character representations. I'm frustrated with chron, because 'seconds' are required to create a time object (my input data never has seconds). More importantly, I cannot make chron print the format 12/30/2006 (which my output data requires).
I really like the format flexibility of strftime() and strptime(), but of course am paranoid about timezone issues. After reading the standard reference several times (http://cran.r-project.org/doc/Rnews/Rnews_2004-1.pdf), I am tempted to conclude that if I never specify timezones, and never use Sys.time(), the vulnerabilities do not pertain. To the point: if I'm merely converting to and from character data that does not represent time zones, is there still a time zone vulnerability with strftime() and strptime()?
