How important is it that the time on my mining rig be accurate?  If it's off by a few minutes, would that affect anything like number of rejected blocks for instance?

The spec says that a node should refuse a block if the timestamp is more than 2 hours into the future.  If the timestamp is too far into the past, I'm guessing that most nodes will also reject it (since it would appear to be older than a block already accepted as valid).

Which brings me to an interesting question.  Why the hell isn't accurate NTP timekeeping required of nodes?  If your clock is even 5 minutes into the future, you don't belong on the internet, much less participating in a distributed cryptocurrency.

That would be true if he is mining solo.

If he is part of a pool, I do not believe it is required as the pool is generating the timestamps he would be hashing.
