Does UNIX time record Timezone?
POSIX 7 defines it as (emphasis mine):
If the year is >=1970 and the value is non-negative, the value is related to a Coordinated Universal Time name according to the C-language expression, where tm_sec, tm_min, tm_hour, tm_yday, and tm_year are all integer types:
tm_sec + tm_min*60 + tm_hour*3600 + tm_yday*86400 +(tm_year-70)*31536000 + ((tm_year-69)/4)*86400 -((tm_year-1)/100)*86400 + ((tm_year+299)/400)*86400So it is always relative to UTC, and thus does not encode timezone information.
