Get time in milliseconds using C#
...w.Ticks / TimeSpan.TicksPerMillisecond;
This is actually how the various Unix conversion methods are implemented in the DateTimeOffset class (.NET Framework 4.6+, .NET Standard 1.3+):

How to calculate the difference between two dates using PHP?
...see jurka's answer below
You can use strtotime() to convert two dates to unix time and then calculate the number of seconds between them. From this it's rather easy to calculate different time periods.

In the nearly 40 years that I've been using Unix-like systems it has never occurred to me that you could put the redirect anywhere but at the end. Putting it up front like this makes it much more obvious (or "facilitates reading" as @MarcoAurelio says). +1 for teaching...
Accurate way to measure execution times of php scripts

microtime — Return current Unix timestamp with microseconds
If get_as_float is set to TRUE, then microtime() returns a float, which represents the current time in seconds since the Unix epoch accurate to the nearest microsecond.

Just a quick reminder for those trying to use shell_exec on a
