问题
We are using the Google Calendar v3 API to return a list of events for a user that have been updated since a point in time.
In the v2 API there was no limitation on setting this date in the past.
If we set the UpdatedMin to a date too far back (like 2 months) then the error is thrown
"The requested minimum modification time lies too far in the past. [410]"
If we set ShowDeleted to false then we do not get the error.
I cannot find any reference to a limitation here. Does anybody know the details of this limit. Unfortunately when synchronising calendars this is a show stopper when synchronisation has not run for a period of time for a calendar (other than running a full list which we would prefer to avoid)
EventsResource.ListRequest lr = new EventsResource.ListRequest(service, c.uc.calendar);
lr.UpdatedMin = c.primaryModTime.ToLocalTime();
lr.ShowDeleted = true;
Events el = lr.Execute();
if (el.Items.Count > 0)
{
the following also discusses this issue but without any resoluton.

There is some explanation at:
https://developers.google.com/google-apps/calendar/v3/sync
It says that on 410 you should wipe your storage and perform a full sync instead.
Also consider switching to sync tokens as recommended in the last paragraph.
