Hi! I ran the code
(d <- strptime("1970-01-01 12:00:00 UTC", "%Y-%m-%d %H:%M:%OS", tz =
""))
is.na(d)
dput(unclass(d))
as.POSIXct(d)
(d <- is.na(strptime("1970-01-03 12:00:00 UTC", "%Y-%m-%d %H:%M:%OS",
tz = '')))
is.na(d)
dput(unclass(d))
as.POSIXct(d)
on «R 4.2.3-1 on Linux 6.2.11-arch1-1» and
«R 4.1.0 on FreeBSD 13.0-RELEASE #0 releng/13.0-n244733-ea31abc261f,»
yielding the same result:
[1] "1970-01-01 12:00:00 CET"
[1] FALSE
list(sec = 0, min = 0L, hour = 12L, mday = 1L, mon = 0L, year = 70L,
wday = 4L, yday = 0L, isdst = 0L, zone = "CET", gmtoff =
NA_integer_)
[1] "1970-01-01 12:00:00 CET"
[1] FALSE
[1] FALSE
FALSE
Error in as.POSIXct.default(d) :
do not know how to convert 'd' to class “POSIXct”
Calls: as.POSIXct -> as.POSIXct.default
Execution halted
Best,
Rasmus
