There + is no clock change associated with the transition. + + Changes to build procedure + + The new DATAFORM macro in the Makefile lets the installer choose + among three source data formats. The idea is to lessen downstream + disruption when data formats are improved. + + * DATAFORM=vanguard installs from the latest, bleeding-edge + format. DATAFORM=main (the default) installs from the format + used in the 'africa' etc. files. DATAFORM=rearguard installs + from a trailing-edge format. Eventually, elements of today's + vanguard format should move to the main format, and similarly + the main format's features should eventually move to the + rearguard format. + + * In the current version, the main and rearguard formats are + identical and match that of 2018c, so this change does not + affect default behavior. The vanguard format currently contains + one feature not in the main format: negative SAVE values. This + improves support for Ireland, which uses Irish Standard Time + (IST, UTC+01) in summer and GMT (UTC) in winter. tzcode has + supported negative SAVE values for decades, and this feature + should move to the main format soon. However, it will not move + to the rearguard format for quite some time because some + downstream parsers do not support it. + + * The build procedure constructs three files vanguard.zi, main.zi, + and rearguard.zi, one for each format. The files represent the + same data as closely as the formats allow. These three files + are intended for downstream data consumers and are not + installed. Zoneinfo parsers that do not support negative SAVE values + should start using rearguard.zi, so that they will be unaffected + when the negative-DST feature moves from vanguard to main. + Bleeding-edge Zoneinfo parsers that support the new features + already can use vanguard.zi; in this respect, current tzcode is + bleeding-edge. + + The Makefile should now be safe for parallelized builds, and 'make + -j to2050new.tzs' is now much faster on a multiprocessor host + with GNU Make. + + When built with -DSUPPRESS_TZDIR, the tzcode library no longer + prepends TZDIR/ to file names that do not begin with '/'. This is + not recommended for general use, due to its security implications. + (From a suggestion by Manuela Friedrich.) + + Changes to code + + zic now accepts subsecond precision in expressions like + 00:19:32.13, which is approximately the legal time of the + Netherlands from 1835 to 1937. However, because it is + questionable whether the few recorded uses of non-integer offsets + had subsecond precision in practice, there are no plans for tzdata + to use this feature. (Thanks to Steve Allen for pointing out + the limitations of historical data in this area.) + + The code is a bit more portable to MS-Windows.
