225/*
226 * How many years to generate (in zic.c) or search through (in localtime.c).
227 * This is two years larger than the obvious 400, to avoid edge cases.
228 * E.g., suppose a rule applies from 2012 on with transitions
229 * in March and September, plus one-off transitions in November 2013,
230 * and suppose the rule cannot be expressed as a proleptic TZ string.
231 * If zic looked only at the last 400 years, it would set max_year=2413,
232 * with the intent that the 400 years 2014 through 2413 will be repeated.
233 * The last transition listed in the tzfile would be in 2413-09,
234 * less than 400 years after the last one-off transition in 2013-11.
235 * Two years is not overkill for localtime.c, as a one-year bump
236 * would mishandle 2023d's America/Ciudad_Juarez for November 2422.
