New Fixes in This Release

1.

If a user has set up multiple clocks on a server with Fix #214596 installed, all clocks show the client time.

[From XAE500W2K8050][#226599]
2.

The client time zone location as set by the “Estimate client time zone” farm property feature can be incorrect although the time and date are correct. For example, a client device set to the Singapore time zone (GMT+8) might display an accurate time of GMT+8 but display Hong Kong as the time zone location.
