How do I check if the user is using the network time in Android?

how 开发者_高级运维do I check if the user is using the network time or if he changed it himself?

Thanks

If I get your question correctly, checking the following setting would help:

You'll need two permissions: android.permission.WRITE_SETTINGS and android.permission.WRITE_SECURE_SETTINGS
