Keep device date and time synced with Clock Sync 12

If your webOS smartphone is active on a cellular account, you probably have your Date and Time setting to automatically pull from the network connection for the time and time zone. However, if you are running your device without a cellular signal, even if it's connected to Wi-Fi, the network time will be unavailable and the time may start to slip. While a one or two minute difference will not affect your webOS experience, a significant difference will cause some things to break in how you use your phone. The clock and calendar appointments / reminders will be useless and you will be unable to perform actions like refreshing a twitter app or logging in to services like Instapaper because they check the timestamp on your device to make sure nothing unnatural is occurring. Having to manually update the time often can become a frustrating experience, but developer content754 has come to your resuce with Clock Sync, available in the official App Catalog for any webOS device that has App Catalog or App Tucketbox access
Once you install Click Sync, just open up and app and you have the option to perform a onetime sync by tapping the "Sync Now" button. You can also set the app to perform a "periodic sync" every 2, 6, 12 or 24 hours by switching the toggle to ON and selecting your sync time. Alternatively, you can choose a specific fixed time by choosing the "+ Add new time" option under the "@TIME SYNC" section.  Once the app is running, you can tap the  icon to view a history of the time syncs.

If you swipe down from the top-left to view the Application dropdown menu and choose Preferences, you can also choose some addition advanced features as well. You can select to turn on "Monitor Mode" that will not actually change the date and time during a periodic or fixed sync, but rather just keep a history of how far off your time is from the official time. In addition, you decide if you want to show or suppress notifications for when a time sync occurs

Finally you can work with an experimental "Time Shift" feature that will add or subtract a selected number of hours or minutes to your clock's time. If you wanted to use this feature--especially if you do have a cellular signal on your device--make sure that the "Network time" option in the Date & Time app is turned off so this time shift will not be continually reset.

Clock Sync is available in the webOS App Catalog for free and is compatible with all webOS devices running webOS 1.3.5 or higher
