The Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another server or reference time source, such as a radio or satellite receiver or modem. It provides client accuracies typically within a millisecond on LANs and up to a few tens of milliseconds on WANs relative to a primary server synchronized to Coordinated Universal Time (UTC) via a Global Positioning Service (GPS) receiver, for example.
timekpr will track and control the computer usage of your user accounts. You can limit their daily usage based on a timed access duration and configure periods of day when they can or cannot log in. With this application, administrators can limit account login time duration or account access hours. It has support for GNOME, KDE, and XFCE and uses time and access Linux PAM modules. It is currently limited to Ubuntu only.
Dateutils are a bunch of tools that revolve around fiddling with dates and times in the command line, with a strong focus on use cases that arise when dealing with large amounts of financial data. Their target market is shell scripts that need date calculations or calendar conversions, and as such they are highly pipe-able and modeled after their well-known cousins (e.g. dtest vs. test, or dgrep vs. grep).
Ace snow creates a snow falling effect for Titanium apps. It creates animated flakes which fall on the application window starting from a random position at the top of the screen and disappear when they fall below the top of the screen. The flakes animation can be paused and resumed any time. The image, quantity, and speed of the snow flakes are configurable parameters.
Titanium Countdown shows a time countdown in Titanium label objects. It can start a time countdown from given time left to the end. It shows the remaining time in label objects of a Titanium application which display the time left in years, months, days, hours, minutes, and seconds. The object can also pause and resume the time countdown any time.
