Good to hear. My explosive 9yo has no sense of time and struggles with transitions. Naturally, the transitions from something fun to something not so fun are hard for him and can lead to meltdowns. We try to negotiate a time with him (e.g., 5 more minutes of video games then take a shower) and remind him of that time once or twice.

This is not an ideal approach but seems to work better than being forceful, which leads to a 2-hour argument or meltdown.
