As a test case I have code running 'as.POSIXlt(1:10)', which can unfortunately produce non-deterministic results:
TZ=Europe/London R attr(as.POSIXlt(as.numeric(1:10)), 'tzone') # [1] "Europe/London" "GMT" "BST" attr(as.POSIXlt(as.numeric(1:10)), 'tzone') # [1] "Europe/London" "BST" "BST" Is this intended behavior? I don't see this possibility described in any of ?DateTimeClasses, ?strptime, ?timezones, or ?as.POSIXlt. Some caching is mentioned around .sys.timezone, but the above snippets don't have any relationship that I can see.
