Well, clearly I've been smoking some nasty potent sh*t. :-\

/me goes and looks at the spec:

"Bit 0 â Timestamp is precise if this bit is set and correlates to the
time of the error event."

So why are we even printing the timestamp when !precise?

IOW, I think we should do:

if (!(timestamp[3] & 0x1))
printk("%stimestamp imprecise\n", pfx);
else {
sec = ..
min = ...

...
}

and print the actual values only when the timestamp is precise.
Otherwise it has *some* values which could just as well be completely
random. And it's not like we're reporting the error tomorrow - it is
mostly a couple of seconds from logging to the fw pushing it out...
