Deadline Countdown Generator
Your market reach is global. It has 24 hours' worth of timezones. A deadline time in one place is 23 hours wrong at another place.
The Deadline Countdown Code Generator provides timezone-accurate PHP code to paste directly into your web pages.
The published countdown notice is automatic and timezone-accurate for every browser that loads your web pages.
Why not JavaScript instead of PHP?
JavaScript uses the person's computer to determine the timezone.
Computer users are notoriously lax when it comes to setting correct timezones on their computers. Some don't bother setting the clock, even. Or the date.
JavaScript can not be relied on for accurate timezone information because it uses the person's computer for the data.
PHP consults your server for time information. Most servers can indeed be relied on for the correct timezone.
For a live countdown, check a certain checkbox when the web page source code is generated. The generated PHP code will then insert timezone-independent JavaScript into your web pages to update the countdown notice every second — minutes, seconds ticking away on the web page.
