Guessing 2018 or there about - certainly your new c++11 code over the 
boost stuff - but I don't remember the exact timing. We could look at 
the commit messages I guess.

Yes, as I said in answer to Cousin_Ricky, I tripped myself up on using 
the v3.8 branch point for povr as v3.8 beta 1 due a screw up in my 
wrapper script. The latter (now)- with the original boost code does 
return utc - but the %z %Z options in datetime don't work. Sticking with 
v3.8 beta <n> as is - at least as far as my Ubuntu machine goes - is an 
OK option I think.

Other changes to now/datetime could wait for v4.0. But, I'm not sure 
what others see for v3.8.

Complete aside... I have a vague recollection of a compile time 
environment variable for some compiler which let users select whether 
std::time() - the 'c' time - would return utc or local time. But, maybe 
it was a fever dream... :-)
