may be simple but i don't know -- Print current date from C program
I found one difference from my code from yours.
I am using the tm structure in a function instead of main()
My sample code structure is
#include <iostream.h>
#include <iomanip.h>
#include <time.h>
....
int main(int argc, char **argv)
{
.....
display_estHdr_formatted(msg);
.....
}
int displayHdr(istrstream& msg)
{
time_t tt; // Seconds since 1/1/1970
struct tm *tod;
time(&tt);
tod = localtime(&tt);
cout << tod->tm_mon + 1 << "/"
<< tod->tm_mday << "/"
<< tod->tm_year << endl
<< tod->tm_sec << endl;
msg.read(displayBuffer,424);
msg.read(displayBuffer, 9);
return 0;
}
I am using IBM Aix version

time::piece::mysql
Time::Piece::MySQL(3pm) User Contributed Perl Documentation Time::Piece::MySQL(3pm)
NAME
Time::Piece::MySQL - Adds MySQL-specific methods to Time::Piece
SYNOPSIS
use Time::Piece::MySQL;
my $time = localtime;
print $time->mysql_datetime;
print $time->mysql_date;
print $time->mysql_time;
my $time = Time::Piece->from_mysql_datetime( $mysql_datetime );
my $time = Time::Piece->from_mysql_date( $mysql_date );
my $time = Time::Piece->from_mysql_timestamp( $mysql_timestamp );
DESCRIPTION
Using this module instead of, or in addition to, "Time::Piece" adds a few MySQL-specific date-time methods to "Time::Piece" objects.
OBJECT METHODS
mysql_date / mysql_time / mysql_datetime / mysql_timestamp
Returns the date and/or time in a format suitable for use by MySQL.
CONSTRUCTORS
from_mysql_date / from_mysql_datetime / from_mysql_timestamp
Given a date, datetime, or timestamp value as returned from MySQL, these constructors return a new Time::Piece object. If the value is
NULL, they will retrun undef.
CAVEAT
"Time::Piece" itself only works with times in the Unix epoch, this module has the same limitation. However, MySQL itself handles date and
datetime columns from '1000-01-01' to '9999-12-31'. Feeding in times outside of the Unix epoch to any of the constructors has
unpredictable results.
Also, MySQL doesn't validate dates (because your application should); it only checks that dates are in the right format. So, your database
might include dates like 2004-00-00 or 2001-02-31. Passing invalid dates to any of the constructors is a bad idea: on my system the former
type (with zeros) returns undef (previous version used to die) while the latter returns a date in the following month.
