Hy,
stumbled over the following problem while plotting DateTime Objects.
plot(as.POSIXct(c("2021-04-21 00:00:00", "2021-04-21 23:59:59")), c(0,
1), type='l')
arrows(as.POSIXct("2021-04-21 00:00:00", tz="CEST"),
0.3,
as.POSIXct("2021-04-21 00:00:00", tz="CEST"),
0.2,
length=0.07, angle=15)
# arrow at 02:00, why?
arrows(as.POSIXct("2021-04-21 00:00:00"),
0.3,
as.POSIXct("2021-04-21 00:00:00"),
0.2,
length=0.07, angle=15, col='red')
# arrow at 00:00 as expected
as.POSIXct(c("2021-04-21 00:00:00", "2021-04-21 23:59:59"))[1]
# [1] "2021-04-21 CEST"
as.POSIXct("2021-04-21 00:00:00", tz="CEST")
# [1] "2021-04-21 CEST"
as.POSIXct("2021-04-21 00:00:00")
# [1] "2021-04-21 CEST"
all representations on my system are the same, why is the plot location
of the arrows different??
I am located in Germany, my locale:
Sys.getlocale()
[1]
"LC_CTYPE=de_DE.UTF-8;LC_NUMERIC=C;LC_TIME=de_DE.UTF-8;LC_COLLATE=de_DE.UTF-8;LC_MONETARY=de_DE.UTF-8;LC_MESSAGES=de_DE.UTF-8;LC_PAPER=de_DE.UTF-8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=de_DE.UTF-8;LC_IDENTIFICATION=C"
Any Idea?
Best regards
Tilmann
