• On not having a separate /boot filesystem on modern (x86) Linux

  The date() function in PHP allows you to print the date and time using the specified format.

  You can get the date and time from any point by specifying a Unix timestamp. However, if you don’t specify a timestamp, then the date() function will use the current date and time as retrieved from the “time()” function.
