[tz] Fwd: Bulletin C number 58

[Paul Eggert]

Thanks, I installed that into the development version on GitHub.

I see that the updated file has a space at the end of the '#@ 3802291200' line 
that encodes the expiration (2020-06-28 00:00:00 UTC). I assume this was 
inadvertent. It doesn't break tzcode (which ignores that line), but the format 
of the line is not documented anywhere that I can see. I dropped Judah Levine a 
line about this.
