texlua ./timeofday.lua

I also tried

texlua --shell-escape ./timeofday.lua

Same result.

TZ is passed to the env.: local function time_of_day (TZ) os.setenv('TZ', TZ) local time = os.gettimeofday(); print(os.date('%c %p', math.floor(time))) print(TZ); os.execute("date +%c") ; print() os.setenv('TZ', nil) end under linux os.date calls localtime_r (if the string format doesn't start with '!') and localtime_r "need not set tzname, timezone, and daylight" I think that this means that the tz info are read only the first time See e.g. https://jianewyork.blogspot.com/2018/03/use-of-localtime-localtimer-and-thei... -- luigi
