FnDate is a function hub class containing a lot of static methods to work with Date objects. Those static methods return functions that take a Date object either as its input or output (depending on the function). It includes conversions to String, to Date and adding days to a Date among others.

| timeInMillisToDate | Function<Long,Date> | int truncateField | Converts the target Long (representing a time in milliseconds) into a Date, truncating by the specified field (java.util.Calendar constant field). |
| timestampToDate | Function<Timestamp,Date> | Converts the target java.sql.Timestamp into a Date. | |
| timestampToDate | Function<Timestamp,Date> | int truncateField | Converts the target java.sql.Timestamp into a Date, truncating by the specified field (java.util.Calendar constant field). |
| toCalendar | Function<Date,Calendar> | ||
| toCalendar | Function<Date,Calendar> | int truncateField | |
| toStr | Function<Date,String> | String pattern | Converts the target Date into a String using the specified pattern. The pattern has to be written in the java.text.SimpleDateFormat format. As no locale is specified, if pattern includes locale-dependent texts like month names (MMM) or week days (EEE), the default locale will be used for resolving these components. |
