Hello,

Or %H, it also works.

strptime("05/01/18 00:59:59 AM", format = ("%m/%d/%y %H:%M:%S %p"), tz="Asia/Jayapura")
#[1] "2018-05-01 00:59:59 WIT"


Hope this helps,

Rui Barradas

Nice catch, Petr:

strptime("05/01/18 00:59:59 AM", format = ("%m/%d/%y %I:%M:%S %p"),
tz="Asia/Jayapura")
[1] NA
strptime("05/01/18 12:59:59 AM", format = ("%m/%d/%y %I:%M:%S %p"),
tz="Asia/Jayapura")

Hi

Maybe it is connected to
%I
Hours as decimal number (01–12).

Your input has hour as 00

Dear members... are these results normal ?

For the first one, no problem. I expected this:

strptime("05/01/18 01:00:00 AM", format = ("%m/%d/%y %I:%M:%S %p"),
tz="Asia/Jayapura")
[1] "2018-05-01 01:00:00 WIT"

For this one, it is ok also:

strptime("05/01/18 01:00:00 AM", format = ("%m/%d/%y %I:%M:%S %p"),
tz="Asia/Jayapura")-1
[1] "2018-05-01 00:59:59 WIT"

But how to explain this ???

strptime("05/01/18 00:59:59 AM", format = ("%m/%d/%y %I:%M:%S %p"),
tz="Asia/Jayapura")
[1] NA

Thanks for your advices
Marc
