I tried correcting the timezone by adding back the difference, but I keep getting assertion error and I have no idea why. I thought it was the type initially, but whatever I change it to, number/string, it still crashes.

Okay I think it's ready

import panel as pn
import datetime

pn.extension()

def change(event):
    time_picker.value = datetime.time(hour=4, minute=8)

def print_picker(value):
    print(value)

time_picker = pn.widgets.TimePicker(value=datetime.time(hour=18, minute=8), format="H:i")
pn.bind(print_picker, time_picker, watch=True)
button = pn.widgets.Button(name='Change Time', on_click=change)
pn.Row(time_picker, button).servable()

Maybe worth adding a test for a different timezone: microsoft/playwright#26996
