Hi,
I'm having two fields in the file
F1|F2
20111220|102000
F1 ->YYYYMMDD
F2 ->HHMMSS
Now, I need to compare this with current date & time and need to return the difference value in hours. Already, I checked with datecalc from the forum. So, need hints from Shell Gurus.
Thanks (10 Replies)

ftime
FTIME(3) Linux Programmer's Manual FTIME(3)NAME
ftime - return date and time
SYNOPSIS
#include <sys/timeb.h>
int ftime(struct timeb *tp);
DESCRIPTION
This function returns the current time as seconds and milliseconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC). The time is returned
in tp, which is declared as follows:
struct timeb {
time_t time;
unsigned short millitm;
short timezone;
short dstflag;
};
Here time is the number of seconds since the Epoch, and millitm is the number of milliseconds since time seconds since the Epoch. The
timezone field is the local timezone measured in minutes of time west of Greenwich (with a negative value indicating minutes east of Green-
wich). The dstflag field is a flag that, if nonzero, indicates that Daylight Saving time applies locally during the appropriate part of
the year.
POSIX.1-2001 says that the contents of the timezone and dstflag fields are unspecified; avoid relying on them.
RETURN VALUE
This function always returns 0. (POSIX.1-2001 specifies, and some systems document, a -1 error return.)
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

CONFORMING TO
4.2BSD, POSIX.1-2001. POSIX.1-2008 removes the specification of ftime().
This function is obsolete. Don't use it. If the time in seconds suffices, time(2) can be used; gettimeofday(2) gives microseconds;
clock_gettime(2) gives nanoseconds but is not as widely available.
BUGS
Early glibc2 is buggy and returns 0 in the millitm field; glibc 2.1.1 is correct again.
