Converting regular time to CTIME
Does anyone know of an easy way to convert regular time 08/21/2002 @ 8:21:21 pm to ctime. I need this to complete a script that I am writing.
Your expertise and help would be amost appreciated. Please note - I am not a programmer so c-code etc will not help. A utility that can be run from a commnd line or an easy script for unix would help a great deal.
Thanks.

pmctime
PMCTIME(3) Library Functions Manual PMCTIME(3)
NAME
pmCtime - format the date and time for a reporting timezone
C SYNOPSIS
#include <time.h>
#include <pcp/pmapi.h>
char *pmCtime(const time_t *clock, char *buf);
cc ... -lpcp
DESCRIPTION
pmCtime is very similar to ctime(3), except the timezone used is the current ``reporting timezone'' (rather than the default TZ environment
variable scheme), and the result is returned into a caller-declared buffer (rather than a private buffer).
Like ctime(3) the time to be converted is passed via clock, and the result in buf is fixed width fields in the format:
Fri Sep 13 00:00:00 1986
The result buffer buf must be at least 26 bytes long, and no attempt is made to check this. pmCtime returns buf as the value of the func-
tion.
The default current reporting timezone is as defined by the TZ environment variable, so pmCtime and ctime(3) will initially produce similar
encoding of the date and time.
Use pmNewZone(3), pmNewContextZone(3) or pmUseZone(3) to establish a new current reporting timezone that will effect pmCtime but not
ctime(3).
