This removes the necessity to use an external program (nawk, perl) and makes only use of standard (ksh-)features. Anyways, i am glad you have a solution that works.
I hope this helps.

Hi bakunin,
The date +%T output gives you hours, minutes, and seconds (on a 24 hour clock) since midnight in the current timezone. The desired date +%s (which is not available on many UNIX systems, including AIX) gives you seconds since the Epoch (midnight at the start of January 1, 1970 UCT). You need a lot more information than what is provided by the current 24 hour clock time to convert that output to seconds since the Epoch.

Hi,
In unix the command "date +%s" displays the date-time in seconds since â00:00:00 1970-01-01 UTCâ (a GNU extension)
when executed on unix:

It is required to calculate time difference in seconds between epoch time (19700101 00:00:00) and any given date time (e.g. 20010214 14:30:30).
Is there any command in unix to get it? Thanks in adv. (1 Reply)

hi guys,
i need to know how to get the current date/time in seconds and i want to be able to do this in a one liner. like say for instance, if want to get what the time is right now, i'll issue a command like this:

I have a list of time spans in seconds, and want to compute the time span
as hh:mm:nn
I am coding in bash and have coded the following. However, the results are
wrong as "%.0f" rounds the values.
Example:
ftm: 25793.5
tmspan(hrs,min,sec): 7.16 429.89 25793.50
hh: 7

ctime
CTIME(2) System Calls Manual CTIME(2)NAME
ctime, localtime, gmtime, asctime, timezone - convert date and time to ASCII
SYNOPSIS
#include <u.h>
#include <libc.h>
char* ctime(long clock)
Tm* localtime(long clock)
Tm* gmtime(long clock)
char* asctime(Tm *tm)
/env/timezone
DESCRIPTION
Ctime converts a time clock such as returned by time(2) into ASCII (sic) and returns a pointer to a 30-byte string in the following form.
All the fields have constant width.
Wed Aug 5 01:07:47 EST 1973
Localtime and gmtime return pointers to structures containing the broken-down time. Localtime corrects for the time zone and possible day-
light savings time; gmtime converts directly to GMT. Asctime converts a broken-down time to ASCII and returns a pointer to a 30-byte
string.
typedef
struct {
int sec; /* seconds (range 0..59) */
int min; /* minutes (0..59) */
int hour; /* hours (0..23) */
int mday; /* day of the month (1..31) */
int mon; /* month of the year (0..11) */
int year; /* year A.D. - 1900 */
int wday; /* day of week (0..6, Sunday = 0) */
int yday; /* day of year (0..365) */
char zone[4]; /* time zone name */
} Tm;
When local time is first requested, the program consults the timezone environment variable to determine the time zone and converts accord-
ingly. (This variable is set at system boot time by init(8).) The timezone variable contains the normal time zone name and its difference
from GMT in seconds followed by an alternate (daylight) time zone name and its difference followed by a newline. The remainder is a list
of pairs of times (seconds past the start of 1970, in the first time zone) when the alternate time zone applies. For example:
EST -18000 EDT -14400
9943200 25664400 41392800 57718800 ...
Greenwich Mean Time is represented by
GMT 0

The return values point to static data whose content is overwritten by each call.
Daylight Savings Time is ``normal'' in the Southern hemisphere.
These routines are not equipped to handle non-ASCII text, and are provincial anyway.
