Hello

I think this feature can be a useful addition in dealing with time zones. I have applied and tried out the patch, The
featureworks as described and seems promising. The problem with compilation failure was probably reported on CirrusCI
whencompiled on different platforms. I have run the latest patch on my own Cirrus CI environment and everything checked
outfine. 
 

Thank you
