Probably not the cause, but I'm noticing some typos concerning Greenwi(t)ch

Edit

You are asking for the current time in Berlin - which is summer time CEST- and are comparing it to winter time GMT in London.

Both Berlin (CET -> CEST) and London (GMT -> BST) switched to daylight saving time last weekend and are now again 1 h apart.

But Greenwich Mean Time aka GMT (UTC+0) is British time in winter, which is 1h apart from Central European (winter) Time CET.

I hope it's clear now, that you never got CET in the first place, but CEST.

2 weeks ago your code would have seemingly "worked".
