The incredible high OWD for acs-gtfpga -> polito-s2ss is because OWD statistics are collected before we apply the ts hook.

This will be fixed by adding a new (implicit) hook which will replace invalid timestamps before statistics are collected.

This implicit hook function ("fix_ts") has been added by commit 0200f5608e619d58e507a5c86d8b6c58f364b37e.

This is an internal function which means that it will be added to every path implicitly. It will check the value of the timestamp. If it is invalid (0 or -1) we will add the current time.
