Just came across this as well.
In Lightning 1.9, if you extract the XPI, and edit the file
calendar-js/calCalendarManager.js, you'll find the lines below :
if (refreshInterval === null) {
// Default to 30 minutes, in case the value is missing
refreshInterval =
There is another place where the default calendar refresh interval is
set within the contents of the Lightning extension, atleast for 1.9.
Its in chrome/calendar/content/calendar/calendar-properties-dialog.js
The line :
if (refreshInterval === null) refreshInterval = 30;
I changed it to 5,
SOGo 1.3.12C, Thunderbird 10, Lightning 1.2.3. Configured on sogo-integrator
inserting the following line in chrome/content/general/ custom-preferences.js:
force_int_pref(calendar.autorefresh.timeout, 5);
But the refresh time in calendars remain 30 minute. Look at about:config and
find
