Overview

Yes, Mobile Link automatically updates the generator controller for Daylight Saving Time (DST). These updates are applied based on the site location and time zone configured in the user’s Mobile Link account.

The update may not appear immediately on the generator controller or within the Mobile Link app.

How Daylight Saving Time Updates Work

Mobile Link determines the correct time zone and DST status using the site location set in the user’s Mobile Link account. When a DST change occurs:

• Mobile Link updates the generator controller’s time zone setting
• The controller applies the correct time offset once it successfully reports in
• No manual time adjustment is required

---

Expected Update Timeframe

DST updates may take up to one week to appear.

This delay is normal, especially during DST transitions when many generators are reporting and updating at the same time.

---

Factors That May Affect Update Timing

Several factors can impact how quickly the update is reflected:

• High network traffic during seasonal time changes
• Signal strength (weak or inconsistent connectivity can delay updates)
• Reporting intervals, as generators communicate at scheduled times rather than continuously

---

Do I Need to Take Any Action?

No action is required.
As long as the site location and time zone in the Mobile Link account are correct, the generator controller will update automatically once communication occurs.
