Hello,
Dates created with as.POSIXct differ between Windows/Mac and Linux.
Specifically this time that is during a gap when the hour does not exist due
to daylight savings time:
as.POSIXct("2018-03-11 02:09:36", tz="America/New_York")
Gives on Windows:
[1] "2018-03-11 EST"
Gives on Linux (Ubuntu 20.04):
[1] "2018-03-11 01:09:36 EST"
Another issue and difference is that with as.POSIXlt on Linux, the invalid
time is presented:
as.POSIXlt("2018-03-11 02:09", tz="America/New_York")
Gives on Windows:
[1] "2018-03-11 EST"
Gives on Linux:
[1] "2018-03-11 02:09:00 EDT"
(Note that the time provided on Linux does not exist due to daylight savings
time.)
I think that for any invalid time, the result should be the same as an
invalid date: NA is returned.
What is the intended, appropriate time, and what is the best way to fix
this?
Thanks,
Bill
