While parsing extra-info descriptors for the dir bytes analysis, I found that some of them have weird write-history or read-history lines with obviously wrong dates. I wonder what leads to these false reports and if there are more errors like this in extra-info descriptors.

Here are some examples:

Any idea what causes this problem? I didn't find an obvious pattern in these examples. Is it just memory corruption on the relays?
