Abstract
In various implementations, provided are techniques for verifying the accuracy of the network time maintained by a client device. In various implementations, a server can be configured to obtain network time information from a network. A particular client device can also obtain the network time information, and use the network time information to compute a network time for applications executing on the network device. The client device can periodically transmit the network time information to the mirror server. When the mirror server receives the time synchronization information from a client device, the mirror server can compare the client device's network time information to the network time information captured by the mirror server. In this way, the mirror server can verify the client device's time accuracy. The mirror server and/or the client device can subsequently perform a corrective action when the client device's time is not accurate.
