Definition and Usage
The microtime() function returns the current Unix timestamp with microseconds.

microtime(get_as_float);
| Parameter | Description |
|---|---|
| get_as_float | Optional. When set to TRUE it specifies that the function should return a float, instead of a string. Default is FALSE |
Technical Details
| Return Value: | Returns the string "microsec sec" by default, where sec is the number of seconds since the Unix Epoch (0:00:00 January 1, 1970 GMT), and microsec is the microseconds part. If the get_as_float parameter is set to TRUE, it returns a float representing the current time in seconds since the Unix epoch accurate to the nearest microsecond |
