On Thursday the 31th of October, I have installed the beta 3.52. Before all was correct.
The problem is on the default watch face using the rising time field. On the sun and moon widget, it is OK.
On the 1st of November, I notice on the evening that the the rising time for sun on the next day (11-2) will be : 6h33am.
In fact rising time should be at Montréal: 7.33am as it is only on the 2nd of November night that Canada will change it's daylight time.
It seems that the change was made one day earlier Than expected ?
