How to set camerahelper timestamp reset when stop?

ros Camerahelper do not have the timestamp input , not like other ros publish such as odom/laser scan/transform tree/joints states , the ros publisher that have read simulaiton time input, so I can set reset time reset when simualtion stop. But ros Camerahelper do not. So there will have a case other publisher’s time is different with roscamerahelper when i click stop or load another usd file . When i do this, other publisher’s time will reset from 0 , but the camerahelper’s time will continues based on the origin value.
so there is any solution that i can set the ros camerahpler publisher’s time reset when stop ?
