Browsers not staying current with Dreamsicle #348

Closed denvergail closed 9 years ago

denvergail commented 9 years ago

Several users are reporting that their websites are not keeping current with their computer's clock and are static until the next update or 2. Some show "1 min ago" for 5 minutes, then switch to "5 mins ago" for 5 more minutes. Back to "1 min ago". They are not all 1 & 5 (mins ago). Some are 4 & 12. Seen in Chrome & Safari on Mac OSX, and on Windows with IE (v11).

Observing this same "time" problem today using Chrome (Version 39.0.2171.99 m) on Windows 7. (Logging it here since this is a different browser/OS combination than reported so far.) Seeing 1 minute... as a persistent value.

denvergail commented 9 years ago

One minute persistency is a symptom of a different problem also. Have you looked at the time stamps of your latest mongodb record?

from a browser type in websiteURL/pebble

convert the two time stamps to human time to see if they are reasonably close (within minutes) or if there is a larger discrepancy.

My plan to fix this is to display the local time, not the time of the last broadcast. With that we'll be able to calculate the time ago even if the network connection drops.

jasoncalabrese commented 9 years ago

Fix in progress, see https://github.com/nightscout/cgm-remote-monitor/pull/350

sulkaharo commented 9 years ago

Further improvement idea: measure the time between broadcasts and show a warning if the delay is very long.

jasoncalabrese commented 9 years ago

@sulkaharo currently the time ago will change from to yellow after 10 minutes and then red after 20 minutes, I could see adding an alarm for that, but probably best as a new feature

Were you thinking of something else?

I have 5 browsers opened (Windows 8, Mac OS X) displaying my NS main screens throughout the house. If I hit refresh on just 1 of the 5 opened browsers (such as from my laptop)...it will instantly update "x min ago" on all 5 of my main screens up to that particular minute.
