Attached is a proposed patch to do that, by slightly extending the syntax of Rule lines so that an entry in their SAVE columns can have an 's' suffix if you want the corresponding rule to specify standard time. For completeness, the new 'd' suffix specifies daylight saving time.
Considering that this proposal makes the setting of the dst bit an issue that is independent from the circumstance of whether the value of a SAVE entry is zero or not, is it not desirable to completely avoid the use of negative SAVE values to express the dst bit setting, so as to make it easier for parsers of zic source files to follow the changes in the "bleeding edge" format? Also, for systematicness, shouldn't the same suffixes and defaults also be applicable to a numeric entry in the RULE column of ZONE lines? Just my 0.04 $. Michael Deckers.
