rwsf::DateTime

Class rwsf::DateTime represents a date and time, stored in milliseconds, from January 1, 1901 00:00:00:000 UTC. Milliseconds are stored in a 64-bit integral type, which is represented by the global typedef rwsfint64.

rwsf::Locale

rwsf::Locale is an abstract base class. It defines an interface that formats the conversion of strings to and from dates and times. It formats dates (including day and month names), times, currency, and numbers (including digit grouping).

rwsf::LocaleSnapshot

The class rwsf::LocaleSnapshot implements the rwsf::Locale interface using Standard C Library facilities. To use it, the program creates an rwsf::LocaleSnapshot instance. The constructor of the instance queries the program's environment (using Standard C Library functions such as localeconv(), strftime(), and, if available, vendor specific library functions) to determine the formatting conventions in effect at the moment of instantiation. When done, the locale can then be switched and another instance of rwsf::LocaleSnapshot created.

rwsf::TimeSpan

rwsf::TimeSpan represents a period as defined by ISO8601. The serialized version of this type takes the format PnYnMnDTnHnMnS, where nY represents the number of years, nM the number of months, nD the number of days, T is the date/time separator, nH the number of hours, nM the number of minutes, and nS the number of seconds. The number of seconds can include decimal digits.

rwsf::TimeZone

rwsf::TimeZone is an abstract base class. It defines an interface for time zone issues such as whether or not Daylight Saving Time is in use, the names and offsets from GMT (also known as UTC) for both standard and Daylight Saving Times, and the start and stop dates for Daylight Saving Time, if used. Note that because it is an abstract base class, there is no way to actually enforce these goalsthe description here is merely the model of how a class derived from rwsf::TimeZone should act.

rwsf::TimeZoneSimple

rwsf::TimeZoneSimple is an implementation of the abstract interface defined by class rwsf::TimeZone. It implements a simple Daylight Saving Time rule sufficient to represent all historical U.S. conventions and many European and Asian conventions. It is table-driven and depends on parameters given by the struct DaylightRule, which is discussed later in this class.
