The date and time on my S5 did a changeover and now reads Wednesday 01-Sept at 00:20 ( now ). I have the auto date|time to Suunto app set to true and battery saver turned on.
The watch time was correct this morning before a bicycle training, I noticed the error after finishing. The watch has not synced to SuuntoApp yet, as my S9 is the current connected watch.
Thoughts on debugging or just ignore? Best guess is the training will be stored on 01-Sept date and the watch will be auto-corrected to present during the sync.
