The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z).Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but 'epoch' is often used as a synonym for Unix time.Some systems store epoch dates as a signed 32-bit integer, which might cause problems on January 19, 2038 (known as the Year 2038 problem or Y2038).The converter on this page converts timestamps in seconds (10-digit), milliseconds (13-digit) and microseconds (16-digit) to readable dates.
This guide describes the installation of a digital-to-analog converter box with your current antenna and analog TV. This guide will help you prepare so that when you purchase a converter box you will know what to expect and whether you may need help setting it up.
Supplies: You will need your analog TV, the antenna you have been using (indoor or outdoor), and the coaxial wire that currently connects your antenna to your TV (as pictured on the right). Your new converter box will come with a coaxial wire and a remote control. Before you begin the installation of the converter box, you should unplug your TV.
For instructions on how to connect your converter box if it does not include an analog pass-through feature or for instructions on connecting your converter box to other components such as a VCR, go to www.fcc.gov/digital-television or contact the FCC by calling 1-888-CALL-FCC (1-888-225-5322) voice or 1-888-TELL-FCC (1-888-835-5322) TTY.

In the String Formatting article, you saw how you can use the StringFormat property of a data binding to convert any type into a string. For other types of conversions, you need to write some specialized code in a class that implements the IValueConverter interface. (The Universal Windows Platform contains a similar class named IValueConverter in the Windows.UI.Xaml.Data namespace, but this IValueConverter is in the Xamarin.Forms namespace.) Classes that implement IValueConverter are called value converters, but they are also often referred to as binding converters or binding value converters.
The Enable Buttons page in the Data Binding Demos sample demonstrates how to use this value converter in a data binding. The IntToBoolConverter is instantiated in the page's resource dictionary. It is then referenced with a StaticResource markup extension to set the Converter property in two data bindings. It is very common to share data converters among multiple data bindings on the page:
The Enable Buttons page demonstrates a common need when a Button performs an operation based on text that the user types into an Entry view. If nothing has been typed into the Entry, the Button should be disabled. Each Button contains a data binding on its IsEnabled property. The data-binding source is the Length property of the Text property of the corresponding Entry. If that Length property is not 0, the value converter returns true and the Button is enabled:
Some value converters are written specifically for particular applications, while others are generalized. If you know that a value converter will only be used in OneWay bindings, then the ConvertBack method can simply return null.
You can write value converters to be more generalized and to accept several different types of data. The Convert and ConvertBack methods can use the as or is operators with the value parameter, or can call GetType on that parameter to determine its type, and then do something appropriate. The expected type of each method's return value is given by the targetType parameter. Sometimes, value converters are used with data bindings of different target types; the value converter can use the targetType argument to perform a conversion for the correct type.
The Switch Indicators page demonstrates how it can be used to display the value of a Switch view. Although it's common to instantiate value converters as resources in a resource dictionary, this page demonstrates an alternative: Each value converter is instantiated between Binding.Converter property-element tags. The x:TypeArguments indicates the generic argument, and TrueObject and FalseObject are both set to objects of that type:
The Binding class defines a ConverterParameter property, and the Binding markup extension also defines a ConverterParameter property. If this property is set, then the value is passed to the Convert and ConvertBack methods as the parameter argument. Even if the instance of the value converter is shared among several data bindings, the ConverterParameter can be different to perform somewhat different conversions.
To display these as hexadecimal values in XAML, they must be multiplied by 255, converted to an integer, and then formatted with a specification of "X2" in the StringFormat property. The first two tasks (multiplying by 255 and converting to an integer) can be handled by the value converter. To make the value converter as generalized as possible, the multiplication factor can be specified with the ConverterParameter property, which means that it enters the Convert and ConvertBack methods as the parameter argument:
The Convert converts from a double to int while multiplying by the parameter value; the ConvertBack divides the integer value argument by parameter and returns a double result. (In the program shown below, the value converter is used only in connection with string formatting, so ConvertBack is not used.)
The California Air Resources Board, with assistance from aftermarket catalytic converter manufacturers, has been developing a database to store and retrieve information on aftermarket catalytic converters that have been approved for use in California. These catalytic converters comply with the new regulations that became effective January 1, 2009. The database is currently under construction and contains some of the catalytic converters approved for OBD II vehicles. Once finalized, it will also include catalytic converters for non-OBD II vehicles.
*Toyota: Please follow this link to see catalytic converters that are legal on 2001-2004 4.7 liter Toyota Sequoia and 2003-2004 4.7 liter Toyota Tundra. to see catalytic converters that are legal on 2001-2004 4.7 liter Toyota Sequoia and 2003-2004 4.7 liter Toyota Tundra.

The new Blackmagic Micro Converters are incredibly tiny broadcast video converters that let you connect between consumer HDMI and professional SDI equipment. The rugged and miniaturized design makes them small enough to be used anywhere! You get professional 3G-SDI or 12G-SDI connections, depending on the models, so you can work with SD, HD and Ultra HD formats up to 2160p60. Micro Converters use USB for power, so they can be powered directly from televisions or laptop computers. You can even purchase them without power supplies! Only Blackmagic Micro Converters feature custom electronics that conform to global broadcast specifications, and can be updated to new standards in the future.
This model is perfect for connecting HDMI cameras and computers to professional SDI equipment! You get two 3G-SDI outputs which can be set to level A or level B formats. Unlike cheap converters, it even supports feature film video formats including 1080p24, 1080p47.95 and 1080p48.
Unlike other small SDI converters, Blackmagic Micro Converters feature the highest quality broadcast technology, miniaturized into an incredibly strong metal enclosure. Each converter has the highest quality broadcast industry standard SDI and HDMI connectors. Blackmagic Micro Converters include a USB connection for power, as well as for changing settings via the converter utility on Mac and Windows. Because the USB powers the converter, you can even power it from televisions or laptop computers. There are even LEDs for status. You can also buy Blackmagic Micro Converters with an AC power supply including 4 adapters for international use.
For color accurate monitoring, some models include a 3D LUT! You can apply custom looks, color and gamma changes in real time for on set monitoring. Plus LUTs can also be applied to the SDI loop output, allowing you to use the converter as a 3D LUT processor! 3D LUTs are great for allowing a low cost computer monitor or TV to be used as a color calibrated broadcast or grading monitor. 3D LUTs are included on the SDI to HDMI 3G, SDI to HDMI 12G and BiDirectional SDI/HDMI 12G models. You can even use DaVinci Resolve to create custom 3D LUTs! Because DaVinci Resolve can be downloaded free, it costs nothing to start creating your own library of 3D LUTs! Imagine reproducing old film stocks!
