Someone, please enlighten me - what do the numerical numbers in the output of zdump stand for? What I mean is, for this output: [dcotruta@linnoc ~]$ /usr/sbin/zdump -v -c 2008,2009 America/Los_Angeles America/Los_Angeles -9223372036854775808 = NULL <------ What does this line signify? America/Los_Angeles -9223372036854689408 = NULL <------ What does this line signify?

America/Los_Angeles 9223372036854775807 = NULL <------ What does this line signify? The number is far too large to be a standard timestamp, even in milliseconds... so what is it?
