Time Zones

Recurring schedules require IANA time zone IDs.

Supported time zone IDs

The list below is only a set of examples. DurableStack accepts any valid IANA time zone ID.

• UTC
• America/Chicago
• America/New_York
• America/Los_Angeles
• Europe/London
• Europe/Berlin
• Asia/Tokyo
• Australia/Sydney

Windows time zone IDs are rejected.

Common mistake: Central Standard Time, Pacific Standard Time, and other Windows IDs are not valid here. Convert them to IANA IDs such as America/Chicago or America/Los_Angeles.

Catch-up policy

DurableStack supports:

• SkipMissed (default): jump to the current due slot, then continue future slots.
• CatchUp: materialize one missed slot per loop until current.

builder.Services.AddDurableStack(options =>
{
    options.Recurring.CatchUpPolicy = RecurringCatchUpPolicy.SkipMissed;
});

const { runtime } = await createDurableStackPostgres(
  { connectionString: process.env.DATABASE_URL! },
  {
    recurring: {
      catchUpPolicy: "SkipMissed"
    }
  }
);
