#26359 [Opn]: posix_times gives a very large value, not related with the uptime

ID: 26359 Updated by: sniper@php.net Reported By: whooper at dap dot ro Status: Open -Bug Type: POSIX related +Bug Type: Documentation problem Operating System: FreeBSD 4.9 PHP Version: 4.3.3 New Comment: "The function times returns the number of clock ticks that have elapsed since an arbitrary point in the past. For Linux this point is the moment the system was booted. This return value may overflow the possible range of type clock_t." See also: http://www.omc.net/cgi-bin/man.cgi?section=7&topic=clocks This function really isn't reliable to use. Simply put: Don't use it.
