Ros::Timer, will stopping it with .stop() cause its counter to restart?

Hello,

If I declare a basic timer like this:

ros::Timer my_timer = nh.createTimer(ros::Duration(1), callback);

And then I stop it like this (say, 0.5 seconds later):

my_timer.stop();

And then I start it again like this:

my_timer.start();

Will the timer start again at the beginning of its counter (0 sec), or will it start up from where it left off (0.5 sec)?

Thanks!

The timer will start again at the beginning. The stop() method cancels all pending callbacks and lets the timer forget about the time that has already elapsed.
