dev20220331 excessive calls of formatting routine -> sporadic 'GPS fix lost' events

[W-Geronius]

setup: MFD set to display clock page, data arrive from SK .... no further action.
sporadic losses of GPS Fix were observed (LED).

From the debug log I assume a coincidence with exessive calls to formatTime and formatDate
see attached log, 5 ocurrences observed: at lines 5590, 7771, 10823, 17939 and 18395
this system behaviour has not been observed in any previous version!

edit: another log (with a debug text 'GPS fix lost') shows a slightly different picture, but still in context to formatTime / date

a wonky WiFi adapter (based on RTL8192CU) was the culprit, sorry for the bother
