Someone, please enlighten me - what do the numerical numbers in the output
of zdump stand for?

What I mean is, for this output:

[dcotruta at 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?

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?

Many thanks,
