System clock is ahead message appears on Dashboard

Products

• VMware Avi Load Balancer

Issue/Introduction

After user logs in to Avi UI, Dashboard shows this message  - "System clock is ahead by hh:mm " and tells us to check NTP settings. 

 

• This issue only happens when customer uses Chrome and duplicates a tab after being idle for a couple of minutes. 
• This issue not noticed with other browsers - Firefox, Edge, Safari

 

 

Environment

• Avi Load balancer(All Versions)

Cause

This is a race condition between, API call and UI Render of a component, usually seen in a scaled environment. So, this can be simply put as, wrong notification shown to the user, at the right scenario.

Resolution

Engineering notes:

• There is no functional impact, but this can send a wrong info that UI Analytics is degraded due to time mismatch, though it is not.

Workaround:

• Use Safari, Edge or Firefox
• Refreshing the page also removes this message

Fix:

• Engineering has resolved this issue in 31.2.1, 30.2.3, 31.1.2 
• As the issue is trivial, no plans to fix in 22.1.x
