Short Time ("t") Pattern and Long Time ("T") Pattern in LightSwitch 2012

This article describes how to use the Short Time Format Pattern and Long Time Format Pattern in LightSwitch Visual Studio 2012.

Short Time ("t") Format Specifier

The "t" format specifier represents a custom date and time format string. For example, the format string for the culture is "HH:mm".

Long Time ("T") Format Specifier

The "T" format specifier represents a custom date and time format string. For example, the format string for the culture is "HH:mm:ss".

Note that the Date Time Picker and the Date Time Viewer control will ignore the Format Pattern property. Only the TextBox and the Label controls will recognize this property.
