microtime

返回值: 默认返回字符串 “microsec sec” ,其中 sec 为自 Unix 纪元(0:00:00 January 1, 1970 GMT)起的秒数,microsec 为微秒部分。 如果 get_as_float 参数设置为 TRUE,则返回浮点数,表示自 Unix 纪元起精确到微秒的以秒为单位的当前时间。

All these timing scripts rely on microtime which relies on gettimebyday(2) This can be inaccurate on servers that run ntp to syncronise the servers time. For timing, you should really use clock_gettime(2) with the CLOCK_MONOTONIC flag set. This returns REAL
