## s = vrml_TimeSensor (...) - Low-level vrml TimeSensor node
##
## s is a vrml node with possible fields :
## ------------------------------------------------------------------
## TimeSensor {
## exposedField SFTime cycleInterval 1 # (0,inf)
## exposedField SFBool enabled TRUE
## exposedField SFBool loop FALSE
## exposedField SFTime startTime 0 # (-inf,inf)
## exposedField SFTime stopTime 0 # (-inf,inf)
## eventOut SFTime cycleTime
## eventOut SFFloat fraction_changed # [0, 1]
## eventOut SFBool isActive
## eventOut SFTime time
## }
## ------------------------------------------------------------------
##
## Options :
## Beyond all the fields of the node, it is also possible to use the option
##
## "DEF", name : The created node will be preceded by 'DEF name ', so that
## it is further possible to refer to it.
##
