A warm welcome to the Community @rungear. I would like to know if you keep having inconveniences with your Blaze? If you do, could you please be more specific and tell me which is the problem you have? Is the timezone correct? If it isn't, I recommend changing your timezone to a complete different one, sync your tracker, put the correct time and sync your tracker one more time. To change the timezone, you just need to do the following from a computer:
1. Log into your fitbit.com dashboard and click the gear icon in the top right corner.
2. Select “Settings” from the drop-down menu.
3. Scroll down to the Time section and choose the time zone that best reflects your current location. You can also select 12-hour or 24-hour time display format here.
4. Sync your tracker to update your time zone.
I hope this helps, hope to hear from you soon.
