Purpose
Time Variance (formerly Cortex Time Variance) is where a Delivery Service Partner (DSP) compares what the Logistics Portal recorded with what UZIO timesheets say, before payroll runs. UZIO compares each driver's Logistics Portal activity with their UZIO punches automatically and flags the differences. That removes the manual side-by-side check at period close, reduces the risk of paying for hours that were not worked, and surfaces break-compliance problems while they can still be addressed.
This is an Amazon DSP-only feature, fed by Route Data Sync. Data syncs every 30 minutes. The page does not refresh itself, so reload it to see new data.
Who can do this: users whose role includes Time Tracking access on a DSP account. Changing the variance thresholds additionally needs permission to manage Time Tracking, which the Employer Administrator has by default.
Prerequisite: the UZIO Route Data Sync extension must be installed on a workstation and signed in to the Logistics Portal. Without it, no Logistics Portal data reaches this page. See Setting Up Route Data Sync.
What Route Data Sync does for you
- Timesheets reconcile themselves. UZIO hours against Logistics Portal hours, per driver, per day, with differences flagged for review.
- Issues are tagged automatically. Clock-in and clock-out differences, break differences, deliveries recorded during a break window, and activity recorded while the driver was off the clock.
- You act in one place. Send a pre-filled Email, SMS or Push message to the driver from a flagged row, or open their timesheet to correct a punch.
- Shifts can build themselves. When Enable shift auto-sync is on, routes published in the Logistics Portal appear on your UZIO Schedule as Draft shifts for you to publish. This setting is off by default on newer accounts. See Setting Up Route Data Sync.
Note: Your Logistics Portal data is safe. The extension is read-only and never changes anything in the Logistics Portal. Your Amazon password is never stored in UZIO, because the extension reads the Logistics Portal through your own signed-in browser session. All data travels encrypted.
The two views
Go to Time Tracking > Time Variance. Switch views at the top of the page.
- Details View shows one row per time entry: the UZIO Punches beside the Logistics Portal Punches, break issues, and the tags that explain each flag. Click an N Issues link in the Breaks column to compare each break side by side.
- Daily Total View shows one row per driver per day, with summary totals across the top: scheduled hours, actual hours in each system (UZIO Hours and Logistics Portal Hours), and the net variance.
Filter with the toolbar by pay group, period (including a custom date range), employee, and tag or status, then click Apply.
What counts as a variance
A variance is a difference larger than the threshold your company has set. UZIO keeps three separate thresholds, all on Time Tracking Settings > Route Data Sync:
| Threshold | What it compares |
|---|---|
| Clock-in variance | UZIO clock-in time against the Logistics Portal sign-in time |
| Clock-out variance | UZIO clock-out time against the Logistics Portal sign-out time |
| Break variance | UZIO break-in and break-out times against the Logistics Portal break-in and break-out times |
Each one defaults to 10 minutes and accepts any value from 0 to 120 minutes. A difference within the threshold is treated as a match. A larger difference is flagged for review.
Common mistake: Reading a flagged row as proof of a problem without checking your own thresholds. Tight thresholds flag ordinary rounding; loose thresholds hide real gaps. Check the setting before you act on the pattern.
Acting on a flagged row
- Notify (three-dot menu) sends the driver a pre-filled message by Email, SMS or Push. You can edit it before sending.
- Click the driver's name to open their timesheet at the right pay period and correct the punch. Corrections are always made on the timesheet, never on the Variance page.
Mapping drivers (when needed)
UZIO matches Logistics Portal drivers to UZIO employees automatically, using first name, last name, date of birth, and either the phone number or the personal email address. A driver whose details do not match on those fields cannot be matched, and appears on the Unmapped Delivery Associates tile on your dashboard. Until a driver is mapped, their shifts and hours do not flow into UZIO.
- Open the Unmapped Delivery Associates tile from your dashboard. It lists UZIO employees with no Logistics Portal link.
- Click Map Employee on the employee's row.
- Enter their 14-character Transporter ID and click Save.
You can also link a driver from Schedule Sync Issues. Under Driver Not Linked to a UZIO Employee, click Link the driver to an employee, pick the UZIO Employee and click Save. See Resolving Schedule Sync Issues.
Mapping a driver is a one-time step, and their data starts flowing on the next sync. If a driver reappears on the tile later, map them again. To prevent unmapped drivers in the first place, keep the name, date of birth, phone and personal email on the UZIO employee record matching what Amazon holds.
Day-to-day rhythm
- Keep Chrome open and signed in to the Logistics Portal during the workday. If Chrome closes or the session ends, syncing pauses and resumes automatically. No data is lost.
- End of day: wait 30 minutes after the last driver signs out, reload the page, and work through the flagged rows. Notify drivers, or correct timesheets.
- End of pay period: switch to Daily Total View, filter by variance status, and clear the list before running payroll.
What this does not change
- Payroll runs off your UZIO timesheet data. Logistics Portal data is for variance review. No Logistics Portal figure reaches a paycheck on its own, and an uncleared variance does not block a pay run. Clearing the list before payroll is a control you apply, not one the system enforces.
- Corrections count towards your override rate. Every punch an admin rewrites after reviewing a variance counts in the Delivery Associate override percentage. Where the fix belongs with the driver, use Notify and let them correct their own entry. See Manager Override Monitoring.
- The 30-day limit still applies. On DSP accounts UZIO refuses time-entry and pay-period changes older than 30 days. A variance found on an older period is handled as a payroll adjustment, not a timesheet edit. See Reviewing and Correcting Your Team's Timesheets.
- Route changes still flow into UZIO. When a route changes in the Logistics Portal, the matching shift updates. Shifts an employee has clocked in to, and shifts whose times you changed in UZIO, are not overwritten. Anything the sync cannot apply is listed on Schedule Sync Issues. See How Route Data Sync handles your shifts.
Common problems
The extension icon is gray or red
Your Logistics Portal session ended. Sign back in to the Logistics Portal. Syncing resumes on its own.
The last-synced time has not moved in over an hour
Check that Chrome is open, the computer is awake, and the Logistics Portal is signed in.
The numbers look stale
The Time Variance page does not refresh itself, so reload the browser page. The data is not real time. Allow up to 30 minutes for Logistics Portal activity to appear, and 30 to 40 minutes for the very first sync.
A driver is missing from UZIO
Check the Unmapped Delivery Associates tile. They most likely need the one-time mapping above.
A shift did not appear on the Schedule
- Check that Enable shift auto-sync is on under Time Tracking Settings > Route Data Sync.
- If it is, look for the amber banner above the Schedule: "N shifts have syncing issues between …". Click View details to open Schedule Sync Issues, which lists each shift that was not synced and why.
- Common reasons: the driver is not linked to a UZIO employee, the employee already has a UZIO shift at that time, or the shift was deleted in UZIO.
- See Resolving Schedule Sync Issues.
A variance is blank
The day is still in progress. Wait 30 minutes after the driver's last sign-out.
A variance is hours rather than minutes
The driver most likely missed a sign-out on one side. Open Details View and compare the punches.
Everyone suddenly looks flagged, or nobody does
Someone changed a threshold. Check the three variance values under Time Tracking Settings > Route Data Sync.
Can I trigger a sync manually?
Routine syncing is automatic every 30 minutes, and the Time Variance page has no sync button. Reload the page instead. The extension's own setup panel does offer manual sync actions for an immediate pull.
Can more than one admin install the extension?
Yes. UZIO removes duplicate data automatically, so extra installations only add resilience.
Still stuck?
Contact your UZIO Customer Success Manager, or UZIO Support at support@uzio.com or +1-571-601-1752. Send the driver's name and employee ID, the date and pay period, a screenshot of the row, and the Last sync time shown in the extension's Sync Log.
