I wouldn't expect those modules to publicly import unix time function. 
Such functions are found under the core.sys package:


import std.stdio;
import core.sys.linux.time;

// This is publicly imported by core.sys.linux.time:
// import core.sys.posix.time;

void main() {
  time_t t;
  writeln(time(&t));
  writeln(t);
}

The problem is, the location for these functions are not well 
documented. So, I simply grep under /usr/include/dmd and it usually works.

Is unix time function in wrong module?

[Martin via Digitalmars-d-learn]

Hi,

shouldn't the unix time functions be in std.datetime.Date and 
std.datetime.DateTime instead of std.datetime.SysTime?


The documentation states:
- "std.datetime.systime for a point in time with a timezone."
- "std.datetime.date for points in time without timezones."

Unix epoch is 00:00:00 UTC on 1 January 1970 - and UTC is a 
standard, not a timezone.
if i am not mistaken timezones getting applied on UTC - so i do 
not understand why the unix time functions are in the modules 
which are "timezone aware" and not in the modules without a 
timezone awareness.
