Time Left - A function to find out how many days, hours, secs, mins that is left until the target
I was very sad with most of the countdown scripts that I had found that was for php because they didn't support time
for the target. So I needed one very bad and I have looked all over and didn't find one that would do what I wanted,
so I created this one that really works. All you have to do is call the
function time_left($target_month, $target_day, $target_year, $target_hour, $target_min, $target_sec, $target_am_pm)
and it will return the time that it is left until the target. It supports both 12 or 24 hours format. To use the
12 hour format, enter AM or PM in the $target_am_pm. When using the 12 hour format, you can only enter 1 - 12
in the field. To use the 24 hour format, leave the $target_am_pm blank. When using the 24 hour format, you can only
enter 0 - 23 in the field.
24 Hours Format
12AM = 0
1AM = 1
2AM = 2
3AM = 3
4AM = 4
5AM = 5
6AM = 6
7AM = 7
8AM = 8
9AM = 9
10AM = 10
11AM = 11
12PM = 12
1PM = 13
2PM = 14
3PM = 15
4PM = 16
5PM = 17
6PM = 18
7PM = 19
8PM = 20
9PM = 21
10PM = 22
11PM = 23
Error Codes
-1 = There's no time left to the target.
-2 = Error: Month Format Incorrect (Must be in the 1 - 12 range)
-3 = Error: Day Format Incorrect (Must be in the 1 - 31 range)
-4 = Error: Year Format Incorrect (Must be at least 4 chars long and it must be in the 1950 - 2050 range)
-5 = Error: Hour Format Incorrect (If using 12 hour format, must be in the 1 - 12 rnage, if using 24 hour format,
must be in the 0 - 23 range)
-6 = Error: Min Format Incorrect (Must be in the 0 - 59 range)
-7 = Error: Sec Format Incorrect (Must be in the 0 - 59 range)

XML has become a common way of storing business data as flat files and many data server vendors including IBM have provided ways to store this data within relational database systems. Increasingly collections of XML files are accessed like databases using an xQuery and other XML standard mechanisms. Businesses find the need to combine the traditional tabular structured data with XML formatted data. In this webcast, you’ll learn about IBM’s WebSphere Federation Server technology, which provides users with the ability to integrate these two data formats.
