NavList:

There are, well-known to NavList-members, at least three different time zone descriptions.
1) Starting with Z and A,B,C … to the east / N,O,P … to the west.
2) Starting with 0 and -1,-2,-3 … to the east / +1,+2,+3 … to the west. (N.A.)
3) Starting with 0 and +1, +2, +3 … to the east / -1,-2,-3 … to the west (I.S.O.)

The Date-column in the NavList message board has zone descriptions, very often -0700 and -0800 but others too, e.g. +0100 and -0300. After which of the above systems? Don’t say there is a forth.
And why are my messages numbered either -0700 or -0800. Can’t of course reflect my whereabouts. Mine is actually Alfa (N.A. -1, I.S.O. +1). Surely not a great question of general interest; I am just curious about the NavList practice.
