Improve warning message when importing queries from the future (a typical problem of systems starting at 1970-01-01 on every boot). Also, show the warning only once instead of flooding the log file.

Thanks. This is a Github bug. I contacted their service already about it but they seem unwilling to help. The issue is that some emails from Github are rejected by the junk filter and, as a result, Github unverifies my email immediately.

I do not see any notification about it and the "fix" is to simply verify the mail address again. I did that at least 50 times already but it happens again ever 10 days to three months. I'm happy if someone points me to it when I forget about it. It is always (and has always been) the same email address...
