Gabor, I looked at that R News article but can't figure out whether *any* of these classes preserve sub-second resolution (which seems crazy to me; I guess in the case of POSIXt there may be an ANSI standard that specifies that 'seconds' are stored as integers, but otherwise this seems like a needless restriction). Am I missing something?
