A single-purpose Chrome extension for UC Davis Schedule Builder. It shows an optional pass-time countdown and, if enabled, auto-clicks “Register ALL Changes” exactly once when the pass flips while you are on the page.

• Parses the nearest future Pass Time on the page.
• Forces Pacific Time parsing, independent of system timezone.
• Auto-clicks once only when the pass becomes active while you are present. No retries. No spam.
• If the pass was already active on load, it does not click. It prompts you to register manually.

Append ?ucdTest=5 to the Schedule Builder URL (or &ucdTest=5 if it already has parameters) to simulate a pass flip in 5 seconds.

• Automated time-critical class registration used by 300+ students (≈40 weekly active, 100+ during registration periods), using a single-purpose Chrome extension to trigger a one-time, fail-safe registration action at pass-time activation.
