After changing the time in the menu, sometimes the clock on the panel of the 777X doesn't actually update the displayed zulu time. Does anyone else see this?

Todays flight I noticed the clock was all zeros during my cockpit setup.  After about 5 min it suddenly changed to display the proper

Zulu time.  It's the first time I'd noticed this behaviour, and I blamed it on the T7's (as reported) realistic "come to life" / power up

sequences.  Otherwise,  the clock always matches the time set in the FSX menu.
