URGENT PROJECT: PHP project, convert C# Date.Time.Ticks to PHP format and evaluate the result

This project is urgent—please only bid if you can complete it within the next 12-24 hours. I need some PHP code that does the following: 1. Take a variable $t that is a time string in C# [login to view URL] format. More information about this format and how it relates to time in PHP: [login to view URL](v=vs.110).aspx [login to view URL] [login to view URL] 2. Convert this $t to a PHP-recognized date/time format. 3. Evaluate whether the $t time is less than 45 seconds old. 4. If it is less than 45 seconds old: // do stuff 5. If it is more than 45 seconds old: // do nothing
