Abstract:
1. A computing system capable of synchronizing data between devices, the computing system comprising one or more computer-readable media having computer-executable instructions for implementing a method of determining if a value for a property on a remote device has changed since a last synchronization of the property between the remote device and a local machine, wherein the computer executable instructions, when executed by a processor, cause the computing system to perform the following: receive a current value for a remote property and a remote representation for a prior value of the remote property; receive a remote representation of time date information associated with the remote property, wherein the remote representation of the time-date information is one or more of a Hexadecimal number, stored down to the seconds, stored down to the minutes or stored in a time zone independent format; generate a local representation of the remote property from the current value for the remote property; compare the remote representation to the local representation; determine, based on the comparison, that the prior value of the remote property was changed after the remote representation was generated; and based on the determination that the prior value of the remote property was changed, determine that the remote representation of time-date information is potentially unreliable.
