create earlier now is a timeline whose absolute current time is defined by calling the function now.

delay_e stop l d e is an event such that : Occurences are those of e delayed by d units of time on l., No occurences are generated after stop occurs (existing deadlines are removed).

delay_s eq stop l d i s is :

S.hold ?eq i (S.delay stop l d (S.changes s))

now l is the current time on the timeline.

progress exec l immediatly removes the next deadline from the timeline and if exec is true (default) executes it.

stamp stop occ l t is an event such that : A single occurence is scheduled for t on l., The occurence's stamp is occ t t' with t' the occurence time., No occurence is generated after a stop occurs (existing deadlines are removed) or if t is earlier than now l when stamp gets executed.

stamps stop start occ l is an event such that : The first occurence is scheduled for start (defaults to now l)., At each occurence time t, occ start t returns the stamp for the current occurence and the time of the next schedule. If the latter is earlier or equal to t no new occurence is scheduled., No occurences are generated after a stop occurs (existing deadlines are removed) or if start is earlier than now l when stamps gets exectued.

wakeup l is the duration until the next deadline on the timeline (if any).
