Replication data and code for "When to reschedule persistent Quartz triggers after a time zone database upgrade"

The evidence archive (qztz_supporting_information.zip) contains the callback logs, trigger-level correctness records, paired timing and H2 write measurements, and Java implementations used in the study. Its index identifies the evidence for each manuscript table, and an offline Python script verifies the files and reconstructs Tables 1–3. This archive is identical to version 1. Version 2 adds qztz_callback_replay.zip, a standalone reproduction of the Asunción case on Windows x86-64. Its README gives a one-command replay with pinned dependencies. After restoring copies of the same database, direct recovery fires on 6 October 2025 only, while rescheduling fires on both 5 and 6 October.
