Although it is not specified by the POSIX standards and the Single UNIX Specifications, many implementations of the date utility provide a %s format conversion specification that will return Seconds since the Epoch. (i.e., the command:
will return the number of seconds since midnight on the morning of January 1, 1970 GMT.) This is a nice value to use for something like this since it is immune to timezone differences and is not affected by shifts to and from daylight savings time.
Another thing not specified by those standards is the network time protocol daemon. Look for an ntpd man page on your servers. If the man page is present ask your sys admins to be sure it is running on those servers.
I want to write a Kshell program which will start the servers(Oracle,DataIntegrator).
Can anybody help me with this?
I would appreciate your help.
Thanks in advance (0 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This function is obsolete.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.
