The CyanogenMod cLock home and lock screen widget is capable of displaying the time, the weather, upcoming calendar events, and more. It's highly configurable, as you would expect considering the ROM it's associated with, and thanks to popular demand, it's now available in the Play Store as a standalone app. Only now it goes by its original name - Chronus.
Update: The CyanogenMod team has chosen a new name: cLock. According to the Google+ post, the new name was chosen by virtue of its simplicity.
In a post to Google+ titled "Pitfalls of being so big" earlier this evening, the CyanogenMod team informed followers that CM had been served with a C&D (Cease and Desist) request regarding their Chronus clock widget.
For those unfamiliar, Chronus is CyanogenMod's acclaimed lock screen (or home screen) clock widget, introduced last December, that displays the time in Android 4.2 fashion along with configurable calendar and weather information.
CyanogenMod just announced that CM 10.1 builds starting with nightlies released today will be getting a brand-new clock widget called Chronus (initially known as 'Lock Clock'). It works both as a homescreen and lockscreen widget, is configurable, and provides extra information in the form of calendar events and weather.
It works on both phones and tablets, and in lockscreen widget mode, appears collapsed and must be expanded in order to view additional information (this could later change with a settings toggle).
