For Process Builder and Workflow Rules, the minimum time unit for time-dependent actions is 1 hour. For Record-Triggered Flow Scheduled Paths, you can go down to minutes (with a minimum of 1 minute in most contexts).
The numbers
| Tool | Minimum scheduled time | Maximum |
|---|---|---|
| Workflow Rule time-dependent action | 1 hour | Up to your needs (years, if anchored to a far-future date field) |
| Process Builder scheduled action | 1 hour | Same |
| Flow Record-Triggered Scheduled Path | 1 minute (when anchored to “now”), broader granularity with field anchors | Same |
| Schedule-Triggered Flow | 1 minute (cron-style schedule) | — |
Why the 1-hour floor exists in older tools
Workflow and Process Builder were designed before Salesforce’s automation infrastructure had the high-throughput scheduling we have today. The 1-hour floor was a guardrail against admins creating thousands of close-time-spaced queued actions that could overwhelm the queue.
Flow’s Scheduled Paths run on the same modern engine as Schedule-Triggered Flows and Platform Event-Triggered Flows — that engine handles minute-level granularity well, so the floor was relaxed.
How this maps to the next question
The very next interview question is “What if I want the action to fire in 30 minutes?” — see the answer. Short version: use a Flow Scheduled Path, not Process Builder.
What if you genuinely need a 1-minute scheduled action
- Flow Record-Triggered Scheduled Path — built for exactly this
- Apex
System.schedule()with a one-off scheduled class — more control, more code - Platform Event delayed by external system — complex but possible
Other timing limits to know
- Scheduled paths can’t trigger from before-save flows — only after-save
- The triggering record’s owner runs the scheduled action; if that user is deactivated, the action fails
- A single record can have many queued scheduled paths at once — they don’t replace each other unless you build that logic in
What interviewers want
- The number: 1 hour for Workflow / Process Builder
- The exception: Flow supports minutes
- Bonus: that Schedule-Triggered Flows can run as often as every few minutes
