Subject: Uncertain usage/scope of a possibly standard timezone name 'MEZ-1MSZ'


I'm not a member of the distribution list, although I believe my enquiry is covered by its scope, and I wonder whether you might be able to circulate my enquiry (and return any replies) as my own research has failed to identify an answer. 

I'm trying to service a request to recognise the standard timezone name of 'MEZ-1MSZ', but I've so far not found any documentation to support or define the scope if this is an acceptable POSIX TZ value and a standard timezone name. 
The suggestion has been made that MSZ is a widely(?) employed alias (in some region(s) of the Gernan speaking world?) for MESZ that is standardly defined for "Mitteleuropäische Sommerzeit" (GMT+0200); MEZ being an accepted acronym for "Mitteleuropäische Zeit". 
And, I whilst I can find instances for the use of the standard(?) 'MEZ-1MSZ-2' I have been unsuccessful in locating any equivalence for 'MEZ-1MSZ' itself.  Is MSZ equivalent and a widely accepted acronym matching MESZ, and if so where and how typical is its use? 
How does it differ to the 'MEZ-1MSZ-2' standard? 

Can you/anyone advise on the practice of employing 'MEZ-1MSZ' as a POSIX TZ value or indeed how prevalent its use is, or in which region (likely related to honouring DST somewhere in the vicinity of Berlin?) and whether this is directly equivalent to other common/standard names, such as CET-1CEST?  What should its Olson equivalent be? 

(Whilst my inconclusive researches have been more extensive, support for the above statement appears available readily here (amongst other places): 

Thank you in anticipation,
