Interesting that AB should end up in Switzerland, a country very fastidious when it comes to the matter of 'time'.
At an ATC unit SW of POL, a SRATCOH sheet was produced using 'local time'.
The clock above this sheet, also showed 'local time', as it had for 30 years.
Mr. Swiss Control changed the aforementioned clock to show permanent UTC, (because it said so in MATS Pt. 1).
During the unit's busy summer months many ATCOs plugged in very late, because ATCOs are, 'only human'.
Have 'graffiti boards' appeared in Switzerland yet?
