- public int64 from_timeval (TimeVal timeval)
              
              Convert a GLib.TimeVal to an amount of 
                  milliseconds since the Unix Epoch
               
- public TimeVal to_timeval (int64 timestamp)
              
              Write a Zeitgeist timestamp to a GLib.TimeVal
                   instance. Note that Zeitgeist uses only a millisecond resolution, whereas GLib.TimeVal has 
                  microsecond resolution. This means that the lower three digits of @tv.tv_usec will always be 0.
               
- public int64 from_now ()
              
              Return the current timestamp in milliseconds.
               
- public int64 from_iso8601 (string datetime)
              
              Parse a timestamp from an ISO8601-encoded string.
               
- public string to_iso8601 (int64 timestamp)
              
              Convert a timestamp to a human-readable ISO8601 format
               
- public int64 from_date (Date date)
              
              Convert a GDate to a Zeitgeist timestamp
               
- public int64 from_dmy (DateDay day, DateMonth month, DateYear year)
              
              Convert a day, month, year tuple into a Zeitgeist timestamp
               
- public Date to_date (int64 timestamp)
              
              Write a timestamp to a GLib.Date 
                  structure
               
- public int64 next_midnight (int64 timestamp)
              
              Calculate the timestamp for the next midnight after the given 
                  timestamp.
               
- public int64 prev_midnight (int64 timestamp)
              
              Calculate the timestamp for the midnight just before the given 
                  timestamp.
