About delete date calculation for not discovered anymore items (LLD).

Zabbix uses received value for clock to calculate "delete date" for not discovered items (LLD).
The current formula is "Received clock + Keep lost resources period (in days)".
It is better to use formula like "Now + Keep lost resources period (in days)" to avoid any issues. Example, incorrect clock may cause the following:
"The item is not discovered anymore and will be deleted in 19y 11m 7d (on 2035-10-17 at 12:27)".
