Interesting how Unix seems to have done the most with Timezone
handling. My guess is it's because of the Bell Systems interest in
record keeping of CDR's (Call-Detail-Records) for phone billing per
minute charges or message units. They probably kept the records in GMT
and just wrote the local time of call and length on the bills when
processing.
Does anyone know if the assumption is true?
I've never heard that before but I doubt it's true. Most of the interesting
timezone-related work on Unix was done outside of the labs. I think in the
research Unix days it was rather more primitive, and besides, that group
was not focused on telephone billing.
