Last login on info page

I get a last login information like this:
01-01-70 02:00:00

Is this a year 2000 bug or what?

No, it just means you’re getting an empty timestamp. That’s the beginning of the UNIX "epoch", the date all timestamps start from. A timestamp is simply the number of seconds since that date (which means 32-bit systems will run out of time in 2035 or something like that).

This usually happens the first time you log in, since there is no timestamp for your last login, since you’ve never logged in before.
