How can I put they correct time?, because appear the china time
Changing The clock:
1. On your phone, go to "Settings>System>Date and time".
2. Disable "Automatic timezone".
3. Set timezone to "GMT+8:00", by selecting a Chinese city such as "Shenzhen (China)".
4. Disable "Automatic date and clock".
5. Set the clock to your current local time.
6. Close and re-open the Hey+ app. It should sync the clock after a minute.
If the clock on your Hey+ band isn't changing, try unbinging the band (Last option in the settings on the Hey+), and then unbind it from your phone.
Or you may try restarting your Hey+ band, by selecting the 2nd last option in the settings menu.
Note: You may re-enable "Auto timezone", and "Auto date and clock" as long as the Hey+ app is closed. If you open the Hey+ app, the clock will be back to China time.
