TIME(3C)TIME(3C)NAME
time, ftime - get date and time
SYNOPSIS
long time(0)
long time(tloc)
long *tloc;
#include <sys/types.h>
#include <sys/timeb.h>
ftime(tp)
struct timeb *tp;
DESCRIPTION
These interfaces are obsoleted by gettimeofday(2).
Time returns the time since 00:00:00 GMT, Jan. 1, 1970, measured in seconds.
If tloc is nonnull, the return value is also stored in the place to which tloc points.
The ftime entry fills in a structure pointed to by its argument, as defined by <sys/timeb.h>:
The structure contains the time since the epoch in seconds, up to 1000 milliseconds of more-precise interval, the local time zone (measured
in minutes of time westward from Greenwich), and a flag that, if nonzero, indicates that Daylight Saving time applies locally during the
appropriate part of the year.

ftime - get date and time more precisely
SYNOPSIS
Remarks
This facility is provided for backwards compatibility with Version 7 systems. Either or should be used in new programs.
DESCRIPTION
fills in a structure pointed to by its argument, as defined by
/*
* Structure returned by ftime system call
*/
struct timeb {
time_t time;
unsigned short millitm;
short timezone;
short dstflag;
};
The structure contains the time in seconds since 00:00:00 UTC (Coordinated Universal Time), January 1, 1970, up to 1000 milliseconds of
more-precise interval, the local timezone (measured in minutes of time westward from UTC), and a flag that, if nonzero, indicates that Day-
light Saving time applies locally during the appropriate part of the year. Consult gettimeofday(2) for more details on the meaning of the
timezone field.
can fail for exactly the same reasons as gettimeofday(2).
WARNINGS
The millisecond value usually has a granularity greater than one due to the resolution of the system clock. Depending on any granularity
(particularly a granularity of one) renders code non-portable.

Strange behaviour of the strftime() function from gawk (3.1.5):
$ awk 'BEGIN{print strftime("%T", 3600)}'
> 02:00:00
$ awk 'BEGIN{print strftime("%T", 0)}'
> 01:00:00
Obviously something with DST but I can not figure out why? To me 3600 epoch seconds remains 01:00, DST or not.

Hi Everyone
i have a perl file below, one of the line is convert the pcho time to human readable format.
$value=`awk 'BEGIN{print strftime("%c",1273236600)}' | tr -d '\n'`;
if image, if i have lots of pcho time value in a file, if i use this awk, strftime, then tr -d to remove the \n,... (2 Replies)
Hi,
I'm wrote a small program on HPUX that uses wcsftime, but this function seems to be not working - I get 0 as a result, the output buffer returns empty, and errno is 0 :
#include <iostream>
using namespace std;
int main ()
{
size_t formattedTimeLength = 0;
wchar_t formattedTime... (9 Replies)
Hi,
I am facing one strange situation while using strftime() to get current date and time in C.
it leaks memory with %T
strftime(L_StrDate,30,"%d-%b-%C%y %T", localtime((time_t *)&tv.tv_sec)) ;
and when i use another option then no memory leak like
strftime(L_StrDate,30,"%d-%b-%C%y ... (3 Replies)
HI,
i wish to convert a millsec value to a readable string format.
the one option is to use strftime.
However this is a bit costly (1-5 micros).
is there a a faster way to do so with just string manipulation
(Note i have the date object which has the time details but wish o avoid strftime) (2 Replies)
Hello all,
I have the following code that seems to be misbehaving depending on the timezone setting (TZ Environment variable). It gives the correct value when TZ is in POSIX format and the wrong value when in OLSON format.
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

I frequently use awk time functions and am switching some scripts over to mawk. I don't have the mktime or strftime functions in mawk, but it appears that there is a way, as explained here in "Time functions":

So, simple... (10 Replies)
I'm trying to use AWK to filter on some dates in a field by converting them to Unix Time.

My first thought is %d-%b-%Y %H:%M:%Sbut I see the following issues:
