Hi Dave,
 
I agree with your opinion,the first suggestion (1) seems better.I have already accepted your specification and modified the patch. Specific modification as follows:
 
(1)    The option “-t” is accepted, while the option "-c" was abandoned.
(2)    Turn key word '*_clock' into '*_timestamp'.
(3)    Add information about active task on each cpu,like this:
CPU 0: 67393251944103
[67393251944103]  PID: 14776  TASK: ea54aab0  COMMAND: "crash"
CPU 1: 66789719628339
[67393251858710]  PID: 14769  TASK: f4bdc030  COMMAND: "crash"
 
Do you have any other suggestion or requirement?
 
Regards,
Wei Jiangang
