-- Hoogle documentation, generated by Haddock -- See Hoogle, http://www.haskell.org/hoogle/ -- | Time library -- -- This package provides the old time library. For new code, the new time -- library is recommended. @package old-time @version 1.1.0.0 -- | The standard time library from Haskell 98. This library is deprecated, -- please look at <tt>Data.Time</tt> in the <tt>time</tt> package -- instead. -- -- <a>System.Time</a> provides functionality for clock times, including -- timezone information (i.e, the functionality of "<tt>time.h</tt>", -- adapted to the Haskell environment). It follows RFC 1129 in its use of -- Coordinated Universal Time (UTC). module System.Time -- | A representation of the internal clock time. Clock times may be -- compared, converted to strings, or converted to an external calendar -- time <a>CalendarTime</a> for I/O or other manipulations. data ClockTime -- | Construct a clock time. The arguments are a number of seconds since -- 00:00:00 (UTC) on 1 January 1970, and an additional number of -- picoseconds. -- -- In Haskell 98, the <a>ClockTime</a> type is abstract.

The difference -- <tt>d</tt> may be either positive or negative. addToClockTime :: TimeDiff -> ClockTime -> ClockTime -- | converts a time difference to normal form. normalizeTimeDiff :: TimeDiff -> TimeDiff -- | formats time differences using local conventions. timeDiffToString :: TimeDiff -> String -- | formats time differences using local conventions and a formatting -- string.
