Free time zone software for linux

Time::Zone is a miscellaneous timezone manipulations routines.

SYNOPSIS

use Time::Zone;
print tz2zone();
print tz2zone($ENV{TZ});
print tz2zone($ENV{TZ}, time());
print tz2zone($ENV{TZ}, undef, $isdst);
$offset = tz_local_offset();
$offset = tz_offset($TZ);

This is a collection of miscellaneous timezone manipulation routines.
tz2zone() parses the TZ environment variable and returns a timezone string suitable for inclusion in date-like output. It opionally takes a timezone string, a time, and a is-dst flag.

tz_local_offset() determins the offset from GMT time in seconds. It only does the calculation once.

tz_offset() determines the offset from GMT in seconds of a specified timezone.
tz_name() determines the name of the timezone based on its offset

Time Manager is a cgi-bin script that keeps track on how much time you have spent at work. This works with the user signing on and off whenever he or she arrives or leaves.
Time Manager relies heavily on the Date::Manip module which has to be installed before running the script.
Enhancements:
- made a new monthly stats
- reversed change entry list
- actions like signon/off are now linked up with the main menu giving an action-status line at the bottom of the page.
- added some buttons where lists could get long (weekly stats)

TimeTracker is an application loosely based on TimeKeeper, a Windows application used to track the time you spent on a task.

Being a Linux user and not willing to install Wine, I decided to hack my own version.

Time::Warp is a Perl module to control over the flow of time.

SYNOPSIS

use Time::Warp qw(scale to time);

to(time + 5); # 5 seconds ahead
scale(2); # make time flow twice normal

Our external experience unfolds in 3 1/2 dimensions (time has a dimensionality of 1/2). The Time::Warp module offers developers control over the measurement of time.

API

to($desired_time)

The theory of relativity asserts that all physical laws are enforced relative to the observer. Since the starting point of time is arbitrary, it is permissable to change it. This has the effect of making it appear as if time is moving forwards or backward instanteously. For example, on some types of operating systems time starts at Wed Dec 31 19:00:00 1969 (this will likely change as we approach 2030 and with the acceptance of 64-bit CPUs).

to(time + 60*60); # 1 hour ahead

scale($factor)

Changes the speed at which time is progressing.

scale(scale * 2); # double the speed of time

Note that it is not possible to stop time or cause it to reverse since this is forbidden by the second law of thermodynamics.

Time::Beat is a Perl module to convert between standard time and Swatch ".beat" time.

Time::Beat is a module to convert normal time to and from .beats, of which there are a thousand in a day. It can change normal time in time() format to .beats, and .beats into either 24-hour or 12-hour normal time.

SYNOPSIS

use Time::Beat qw(beat time24 time12);

my $time_in_beats = beats($time);

my $beats_in_24hr_time = time24($beat);

my $beats_in_12hr_time = time12($beat);

METHODS

There are three methods in Time::Beat.

beats($time)

beats will give you the current time in .beats if you do not specify a time string. If you specify a string in time() format it will return that particular time in .beats. The basic algorithm for doing this is to take the time in GMT+1 hour, convert it into seconds, and divide by 86.4.

time24($beat)

time24 takes a 3-digit beat time and outputs a 24-hour time along the lines of "12:34:56". The hours will have leading noughts.

time12($beat)

time12 takes a 3-digit beat time and outputs a 12-hour time along the lines of "12:34:56 am" or "12:34:56 pm". Hours do not have leading noughts.

PHP time management project is a Web-based time management application. You can enter scheduled items, copy items, and view them on a calendar.

A few minor items in the login page for the system were fixed.

Time and Attendance is software that is designed to track time and attendance. Attendance tracking is key to any club or organization, and Time and Attendance can easily bring this task online.
Its Web-based interface allows you to enter events as either public or private, and only public events are shown on the public attendance page.
Installation:
-copy all files to your web host
-use phpmyadmin or your mysql interface to run site.sql against your database.
-open site.xml and edit the database section with your database details.
-go to index.php and login with username of admin with a password of test.
-be sure to change the passwords for the admin and regular user.
Setup the site.xml file with your database settings as follows.
< database type="mysql" >
< server >database server address< /server >
< login >database login< /login >
< password >database password< /password >
< default >mysql database name< /default >
< /database >
Add this to your htaccess file to prevent viewing of the xml config file.
< Files ~ ".xml" >

Enhancements:
- Some bugs found in the main form library for the time attendance system were fixed.

Time::Piece is a Perl module that contains Object Oriented time objects.

SYNOPSIS

use Time::Piece;

my $t = localtime;
print "Time is $tn";
print "Year is ", $t->year, "n";

This module replaces the standard localtime and gmtime functions with implementations that return objects. It does so in a backwards compatible manner, so that using localtime/gmtime in the way documented in perlfunc will still return what you expect.

The module actually implements most of an interface described by Larry Wall on the perl5-porters mailing list here: http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2000-01/msg00241.html

USAGE

After importing this module, when you use localtime or gmtime in a scalar context, rather than getting an ordinary scalar string representing the date and time, you get a Time::Piece object, whose stringification happens to produce the same effect as the localtime and gmtime functions. There is also a new() constructor provided, which is the same as localtime(), except when passed a Time::Piece object, in which case its a copy constructor. The following methods are available on the object:

$t->sec # also available as $t->second
$t->min # also available as $t->minute
$t->hour # 24 hour
$t->mday # also available as $t->day_of_month
$t->mon # 1 = January
$t->_mon # 0 = January
$t->monname # Feb
$t->month # same as $t->monname
$t->fullmonth # February
$t->year # based at 0 (year 0 AD is, of course 1 BC)
$t->_year # year minus 1900
$t->yy # 2 digit year
$t->wday # 1 = Sunday
$t->_wday # 0 = Sunday
$t->day_of_week # 0 = Sunday
$t->wdayname # Tue
$t->day # same as wdayname

$t->hms(".") # 12.34.56
$t->time # same as $t->hms

$t->cdate # Tue Feb 29 12:34:56 2000

# of the full POSIX extension)

# see strptime man page. Creates a new
# Time::Piece object
