//! @class Timer 
 
//! @decl static void create( int|void fast ) 
//!   Create a new timer object. The timer keeps track of relative time 
//!   with sub-second precision. 
//!    
//!   If fast is specified, the timer will not do system calls to get 
//!   the current time but instead use the one maintained by pike. This 
//!   will result in faster but somewhat more inexact timekeeping.  
//!   Also, if your program never utilizes the pike event loop the pike 
//!   maintained current time never change. 
 
//! @decl float get() 
//!   Return the time in seconds since the last time get was called. 
//!   The first time this method is called the time since the object 
//!   was created is returned instead. 
 
//! @decl float peek() 
//!   Return the time in seconds since the last time @[get] was called. 
 
//! @endclass 
 
 
 
//! @class Time 
//! 
//! The current time as a structure containing a sec and a usec 
//! member. 
 
//! @decl static void create( int fast ); 
//! 
//! If fast is true, do not request a new time from the system, 
//! instead use the global current time variable. 
//! 
//! This will only work in callbacks, but can save significant amounts 
//! of CPU. 
 
//! @decl int sec; 
//! @decl int usec; 
//! 
//!   The number of seconds and microseconds since the epoch and the 
//!   last whole second, respectively. (See also @[efun::time()]) 
//! 
//!   Please note that these variables will continually update when 
//!   they are requested, there is no need to create new Time() 
//!   objects. 
 
//! @decl int usec_full; 
//! 
//!   The number of microseconds since the epoch. Please note that 
//!   pike has to have been compiled with bignum support for this 
//!   variable to contain sensible values.
