Status: RESOLVED WORKSFORME

(Calendar :: Lightning Only, defect)

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0

Steps to reproduce:

I'm using Lightning add-on for Mozilla Thunderbird 60.2.1 under Linux Mint 18.2.

Actual results:

The red "current time" marker is moving in 15-minute increments.
When the time is 12:59, the red marker will be still on 12:45.

Expected results:

I'd prefer it to be accurate down to 1 minute - so it matches closely current time.
When my clock shows 12:59, I'd expect the red marker to also appear at 12:59, not 12:45.

This value was chosen on purpose to improve performance. To change the value from 15 minutes to something else open Options - General - Advanced Configuration - Config Editor and change the value of the "calendar.view.timeIndicatorInterval" preference. A 0 value will disable the red line.

Thanks!

I'm not sure why making it 1 minute should cause a significant performance hit.
Cron services are checking their tables every minute as well.

I had some trouble finding the setting - it was in:

Main Thunderbird Menu > Preferences > Preferences > Advanced tab > General subtab > Config Editor... (bottom of the page)

I think Thunderbird UI might hang while the calendar view is redrawn and therefore a default value was chosen to not disturb the user too often.
