Good catching, but

In R 4.3.0 on FreeBSD, the same error after changing the period to a colon:

Error in as.POSIXlt.character(x, tz, ...) :
   character string is not in a standard unambiguous format

I copy the code from a web page. It works in R 4.3.0 on Windows and R 
4.1.2 on an old CentOS.


Best,
