Chatgpt keeps time of when you last sent your message

Recently I’ve been trying to improve my workouts but even with heavier weights its too easy so I’ve come to Chatgpt for some help. And it has helped me find workouts, but I believe I count too fast for the workouts I was holding 90 pound dumbbells for static holds but I doubted that I did 150 seconds so I was wondering if Chatgpt could record the time you sent it and came back

As far as I’m aware, no.
It does not natively / openly record the time stamp of your last message, nor can it retrieve current time.
So, it would only be able to tell you the elapsed time if you gave it the time at beginning and again at end, and asked for the time between
