The RULE TYPE column

[Andy Lipscomb]

The "pacificnew" file includes rules with type "uspres" and "nonuspres" to reflect a proposal that would have extended daylight savings time in the US Pacific zone to the Sunday following Election Day in Presidential election years (same as Summer Olympic years). This would be combined with a uniform poll-closing time (within the 48 contiguous states and DC) of 21:00 EST, 20:00 CST, 19:00 MST, and 19:00 PDT. However, since that law was never adopted, the zone in question is commented out, so would not appear in a parsed file.

(If that file is to be retained, it needs to be tweaked anyway, so that the regular rules in it follow the new US style--unless it was already done.)

Subject: The RULE TYPE column

Hi,

Unless I'm missing some of the data files, the only rule TYPE ever used is "-" 

The man page states:
     TYPE    Gives the type of year in which the rule applies.
             If TYPE is - then the rule applies in all years
             between FROM and TO inclusive.  If TYPE is something
             else, then zic executes the command
                  yearistype year type
             to check the type of a year:  an exit status of zero
             is taken to mean that the year is of the given type;
             an exit status of one is taken to mean that the year
             is not of the given type.


What other types except for "-" are allowed?
