Add a new phase called 'delay' with which the initial starting time of a task can be delayed. Parameter is expressed in usec.
Could you add a description of the command in the tutorial.txt document ?
Usage is:
"phases": { "p0": { "delay": 1500000
}, ... other phases ...}
This delay seems to be more a thread's properties than a event : It should be called only once in a dedicated phase You should better parse it and set t_first in the parse_thread_data
