You store the date and time as a formatted datetime string.
This creates a mess.
It is best to store all your dates (as I said) as an integer(11) not a string but since you are storing as a datetime string, that's OK... you can deal with this easily:
The first thing you need to do is to convert that datetime string to a unix timestamp, for example (like this):
I did not test it, but you get the idea. UNIX_TIMESTAMP() will take a formatted string and convert it to unix time.
Quote:
MySQL UNIX_TIMESTAMP() returns a Unix timestamp in seconds since '1970-01-01 00:00:00' UTC as an unsigned integer if no arguments are passed with UNIX_TIMESTAMP().
When this function is used with a date argument, it returns the value of the argument as an unsigned integer in seconds since '1970-01-01 00:00:00' UTC.
The argument may be a DATE, DATETIME,TIMESTAMP or a number in YYYYMMDD or YYMMDD.
Note: Since UNIX_TIMESTAMP() works on the current datetime, your output may vary from the output shown.
consider this as a csv file.

Weather::Com::DateTime(3pm) User Contributed Perl Documentation Weather::Com::DateTime(3pm)NAME
Weather::Com::DateTime - date and time class
SYNOPSIS
#!/usr/bin/perl -w
use Weather::Com::DateTime;
my $gmt_offset = 1; # e.g. for Germany in winter
my $datetime = Weather::Com::DateTime->new($gmt_offset);
$datetime->set_lsup('02/25/05 11:21 PM Local Time');
print "This is the date '02/25/05 11:21 PM' in Germany:
";
print "Epoc: ", $datetime->epoc(), "
";
print "GMT (UTC): ". gmtime($datetime->epoc()). "
";
print "My local time: ". localtime($datetime->epoc()). "
";
print "And finally German time: ", $datetime->time(), " o'clock at ",
$datetime->date(), "
";
DESCRIPTION
Weather::Com::DateTime objects are used to encapsulate a date or time provided by the OO interface (e.g. localtime, sunrise, sunset, etc.).
This is done because there are many ways to use a date or time and to present it in your programs using Weather::Com. This class provides
some predefined formats for date and time but also enables you to easily define your own ones.
These objects always represent the local time of a Weather::Com::Location object. That is, if you have a location object for New York City
and your server running the weather script is located in Los Angeles, for example, this line
print "Sunrise at: ", $location->sunrise()->time(), "
";
will print the time of sunrise (in 24h format) in EST and not corresponding to the timezone of Los Angeles! If you'd like to now what this
is in GMT you could call
print "Sunrise at: ". gmtime($location->sunrise()->epoc()). "
";
or if you want to know when the sun rises at the location in your servers local time than just call
print "Sunrise at: ". localtime($location->sunrise()->epoc()). "
";
There are two ways to get your own date or time format:
1. You use the "formatted()" method and provide a format string to it.
2. If you'd like to define your own "date()" or "time()" method, simply change the corresponding methods.
What you can change in which way without destroying the whole class, is described in section INTERFACE.
CONSTRUCTOR
You usually would not construct an object of this class yourself. This is implicitely done when you call one of the OO interfaces date or
time methods.
The constructor can take a GMT offset in positive or negative hours.
If one calls the constructor without any GMT offset, we assume you want a GMT object.
METHODS
epoc(epoc seconds)
With this method you can set the date and time using epocs (GMT) directly.
It returns the currently set epoc seconds (GMT).
formatted(format)
This method returns a date or time formatted in the way you ask for and corresponding to the local time of the parent object.
The "format" you provide to this method has to be a valid Time::Format format. For details please refer to Time::Format.
set_date(date)
With this method one can set the date of the object using an input format like "Feb 13" which is the 13th of february of the current year.
Using this method, the time is set to 00:00. The year is the current one.
set_time(time)
With this method one can set the time of the object using an input format like "8:30 AM".
The date is set to the current date of the host the script is running on.
set_lsup(lsup)
With this method one can set the date of the object using the weather.com's special last update format that is like "2/12/05 4:50 PM Local
Time".
date()
Returns the date in the format "1. February 2005".
time()
Returns the time in the format "22:15".
time_ampm()
Returns the time in the format "10:15 PM".
weekday()
Returns the day of week with like "Wednesday".
day()
Returns the day in month.
month()
Returns the name of the month.
mon()
Returns the number of the month
year()
Returns the year (4 digits).
