TimeSpan Variable to does not replicate

The Timespan variable does not appear to replicate the changes to the variable to the client from the server (event with the Replication setting set to "Replicated"). In the example a float value has been supplied with the same settings and appears to replicate as expected.

1. Download the attached project
2. Open the project
3. Select Edit > Editor Preferences > Play > Multiplayer Options
4. Set the following Multiplayer Options
   • Number of Players = 1
   • Run Dedicated Server = Checked
   • Use Single Process = Unchecked
   • Editor Multiplayer Mode = Play As Client
5. Play in Editor

Result: The Timespan variable does not appear to replicate the changes to the variable to the client from the server (event with the Replication setting set to "Replicated")
