RFE: Add option to never trust kernel timestamp?

[opty77]

Please consider adding an option (e.g. -u) to never trust kernel timestamp or extending -t with an argument:

• 0: Never trust.
• 1: Always trust (the default).
• 2: Trust only "when starting up the first time". (Probably useless?)

In my VPS provider case, it refers to host boot and not container boot although it may change in the future.

It seems that I could trick syslogd into "never trust kernel timestamp" by creating cache file containing 18446744073709551000 before the daemon starts up the first time.

And it seems to work so another useless option?
