The engine keeps them in UTC, so a fixed time shifts by an hour when the clocks change. The timer list is written into the engine's build as a contract, and the monitor compares the live list to it every minute; a timer added, removed or changed by hand opens an urgent condition within a minute. The checks the monitor runs on its own clocks are on [Monitor checks](/reference/monitor-checks). ## Every minute | Job | What it does | | --------------------------- | ------------------------------------------------------------------------------------------ | | Wake the sync worker | Nudges the worker that carries changes between Zoho and Supabase, in case a queue has work | | Wake the action worker | Nudges the worker that does everything else: QuickBooks, emails, PDFs, pushes, invites | | Wake the evaluator | Nudges the monitor's worker that books every due check and runs the quick ones | | Wake the maintenance worker | Nudges the monitor's worker that runs the slow checks | | Wake the notifier | Nudges the monitor's worker that hands each condition to Sentry | ## Nightly clean-ups | Job | When | What it does | | -------------------------- | ----- | ----------------------------------------------------------------------------------------------------------------------------------------- | | Prune cron history | 23:25 | Drops timer run records older than 7 days | | Prune queue archives | 23:35 | Drops archived queue messages older than 90 days | | Close the call sync window | 00:17 | Marks calls and voicemails over 30 days old as finished with, so the engine stops pushing them to the CRM and an old record is left alone | | Prune integration history | 00:30 | Drops ledger lines older than 13 months and raw vendor notifications older than 90 days | | Sweep property imagery | 01:40 | Queues the Street View fetch for properties still missing an image, 25 at a time | ## Overnight business jobs | Job | When | What it does | | ------------------------- | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Optimise routes | 01:00 | Puts today's stops in driving order for each technician, so nobody criss-crosses the city. It runs only for a day on which some technician holds three or more appointments | | Subscription visit ledger | 02:20 | Asks the action worker to re-derive every live subscription's visit ledger | ## Reminders and pushes | Job | When | What it does | | ------------------------------ | ---------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Open-appointment push | every hour | Looks for appointments still open an hour past their window. Each technician on it gets one push the first hour it is overdue, then one a day at 08:00 until it is completed | | Auto-submit overdue timesheets | 01:00 | Submits every timesheet that is still a draft or was rejected once its submit-by day has arrived, with whatever hours it holds. Super admins are left out | | Timesheet reminder, morning | 09:00 | The day before submit-by: "Timesheet Reminder" push to everyone whose sheet for that period is a draft or does not exist | | Tasks due soon | 09:00 | A push to each task's owner for every task due within the next 24 hours that is not completed or cancelled | | Invoice reminders | 10:15 | Queues a reminder email for every emailed, unpaid invoice seven or more days past due: one at seven days, another at twenty-one | | Appointment reminders | 16:10 | Queues a reminder email for every scheduled appointment tomorrow whose customer has an email and asked to be notified | | Timesheet reminder, evening | 19:00 | The same day, same people: "Urgent: Timesheet Due Now", marked time-sensitive | ## Digests | Job | When | What it does | | ------------------ | ------------- | --------------------------------------------------------------------------------------------------------------------------------------------------- | | Pipeline digest | 08:40 daily | A push, "Pipeline needs attention", to every super admin in the app, listing the pipeline states that have work; nothing is sent when there is none | | Pipeline heartbeat | 08:50 Mondays | A push, "Pipeline monitor alive", to the same people; if it stops arriving, the digest cannot be trusted either | ## The nightly drift sweep The sweep itself runs from GitHub, not from this list. It compares every synced record on both sides and opens a finding for each difference, and closes a finding the next time the two sides agree. See [How sync works](/handbook/running/how-sync-works). * Scheduled at 02:20. GitHub starts a scheduled job when its shared queue reaches it, so the start drifts later. The monitor allows eight hours after the scheduled start, then opens a for-review condition. * The reconciler, which copies Zoho's value over ours for an open finding, has no schedule. A person runs it from GitHub, and it prints what it would write without writing unless told otherwise. * The nightly run goes red when the open findings exceed 160. The findings are still written; the red is the gauge. How to run both by hand is on [Run the sweep and the reconciler](/handbook/running/run-the-sweep-and-the-reconciler). ## Related * [Monitor checks](/reference/monitor-checks) * [How the monitor works](/handbook/running/how-the-monitor-works) * [Sentry](/systems/sentry)
