Does musl support the A. D. Olson "right/" timezones ? I'm not familiar with the "right/" timezones and they're difficult to google for -- please give me a reference for what they are, if you can. However, musl only uses zoneinfo for timezone/daylight-time purposes, not for any sort of adjustment between POSIX/calendar time and UTC(w/leap-seconds) and/or TAI. Perhaps this is the source of the discrepency. Rich
