Hi there,
The following codes may cause the problem in R 4.3.0 on FreeBSD in my
last post: Error in as.POSIXlt.character(x, tz, ...)

In R 4.3.0 on windows,

The only difference is the result of is.na().
Best,
Jinsong
I can't confirm, that is.na(d) returns TRUE on FreeBSD. On my boxes it
always gives
> (d <- strptime("1970-01-01 12:00:00 UTC",
"%Y-%m-%d %H:%M:%OS", tz = ""))
[1] "1970-01-01 12:00:00 CET"
> is.na(d)
[1] FALSE
