Unable to Read Environment Variables from FS2020

[hdinthkld]

Is it possible to read the simulators environment variables (e.g. ZULU TIME)?

Using same code from the demo sample with the below edit:

altitude = sc.get_simdatum("Indicated Altitude")
print("Got indicated altitude", altitude)

absolute_time= sc.get_simdatum("ABSOLUTE TIME")
print(absolute_time)

Results in the following:

According to this document it does say that they available by prefixing with "E:":
PROGRAMMING APIs

The bulk of the simvars I've tried calling appear to only be "A:" variables (e.g. SIM ON GROUND) which work as expected. Reviewing the scvars.json this also seems to be true.

I did find the below bug which could indicate it has been broken since SU14, I don't understand what the OP is saying he did to resolve it:
Simvars of E section not anymore available in SDK

Perhaps this is also of additional assistnace:
