Curiouser and curiouser ...
I rewrote the function R_date (do_date is just a wrapper around R_date)
slightly to make it a standalone program (here i did not replace the
trailing '\n' with '\0', and printed out the result):
#include <stdlib.h>
#include <stdio.h>
#include <time.h>
#include <string.h>
int main(void)
{
time_t t;
char s[26];
time(&t);
strcpy(s, ctime(&t));
printf("%s\n",s);
return(0);
}
The result is [gcc is i386-mingw32msvc-gcc.exe from the gcc-2.95.2-1 mingw
distribution ]:
D:\home\setzer\newstuff\tmp>gcc -o testtime testtime.c
D:\home\setzer\newstuff\tmp>testtime
Mon Jan 22 12:31:17 2001
D:\home\setzer\newstuff\tmp>time
Current time is 12:31:27.89p
Enter new time:
A little later, in R-1.2.1:
date()
[1] "Mon Jan 22 17:32:24 2001"

Am I missing a configuration step? The value returned by date() and
Sys.time() is five hours later than the system time. Furthermore,
Sys.timezone() returns Eastern Daylight Time, whereas we are really
currently in Eastern Standard Time. I am running:

Since you are in time zone -5 (according to your mail headers) it looks as
if you may well have a configuration problem.
It appears that for some reason you are getting UTC rather than your local
time. I have seen this happen under Linux: there's a choice of whether
the real time clock should run local time or should run UTC and have the
system apply the time zone correction. I don't know anything about the
Windows situation, though.
