Hi there! I understand how frustrating it can be when you're trying to log in, and it tells you to calibrate your phone's time. Let's see if we can resolve this issue together.

The message you're seeing usually means that the time settings on your device, in this case, your phone, are not synchronized correctly. Here are a few steps you can follow to calibrate your phone time:

1. Check Date and Time Settings:
- Go to your phone's Settings.
- Scroll down and tap on Date & Time.
- Ensure that Automatic date & time and Automatic time zone are both enabled. This allows your device to set the correct time using the network.

2. Manually Set Time (if automatic settings don't work):
- If automatic settings don't seem to update, disable them and manually set the correct date and time. Make sure it matches the current time zone of your location.

3. Restart Your Phone:
- Sometimes, a simple reboot can resolve syncing issues. After adjusting the settings, restart your phone.

4. Check Your Internet Connection:
- Ensure you have a stable internet connection, as this can also affect the ability to synchronize the time with the server.

After doing these steps, try logging into DMSS again. If you still face the same issue, please let me know, and we can explore further solutions! Are you satisfied with the solution I provided?
