I have Google Timeline turned on and it tracks my movement 24/7. I do find that if I am on the move a lot, then Google’s data is fairly inaccurate. Maybe it is due to how often the system polls my location. Even though storage is cheap, Google cannot store everyone’s data every second… yet.
Looking through my September history, I find the data appears accurate for the days that I go into the office. On those days, I typically leave for work around 7:00 am and come back home after dinner. I assume each data point has a long enough duration for Google to log properly. Here is a summary with departure/arrival times for each trip:
| Date | Leave home | Arrive work | Leave work | Arrive home |
| Sept 6 | 7:39 am | 9:08 am | 6:46 pm | 7:39 pm |
| Sept 7 | 7:20 am | 8:41 am | 5:23 pm | 6:32 pm |
| Sept 8 | 7:12 am | 8:26 am | 6:25 pm | 7:18 pm* |
| Sept 13 | 6:36 am** | 8:10 am | 8:55 pm | 9:39 pm |
| Sept 14 | 7:16 am | 8:25 am | 8:14 pm | 9:02 pm |
| Sept 20 | 7:21 am | 8:24 am | 8:46 pm | 9:27 pm |
| Sept 21 | 7:32 am | 8:44 am | 6:33 pm | 7:35 pm |
| Sept 26 | 6:18 am | 7:07 am | 7:11 pm | 7:57 pm |
| Sept 27 | 6:42 am | 8:09 am | 1:43 pm*** | 2:30 pm |
* I drove to my church cell meeting a restaurant close to home
** I needed to take my sister to LAX so I left home earlier than usual
*** I felt sick that day so left work early to nap at home
If you look at the leave/arrive home columns, I am often out of the house for twelve, thirteen, or fourteen hours. I often find myself extremely tired on both commutes as I still have problems sleeping through the night. This is one of the many reasons I am considering retirement or finding a part-time job close to home.

It is 6:18 am and my Alexa timer is ringing. I need to get ready for another exciting commute to the office.
