I have two questions that I can't seem to find a solution to after looking at std.datetime.

First question is how do I get the current time but in milliseconds?

Second is how do I construct a time ex. systime or datetime based on milliseconds?

Thanks

Unixtime might be what you want:

import std;

import std.datetime;
import std.stdio;

    void main() {
        // Get the current time in the UTC time zone
        auto currentTime = Clock.currTime();

// Convert the time to the Unix epoch (1970-01-01T00:00:00Z)    Duration unixTime = currentTime - SysTime(DateTime(1970, 1, 1), UTC());

        // Get the total milliseconds
        long milliseconds = unixTime.total!"msecs";

        // Print the Unix time in milliseconds
        writeln("Unix time in milliseconds: ", milliseconds);
    }

Thanks a lot.

Also figured out the second question based on your result.

Simply doing:

```
SysTime(DateTime(1970, 1, 1), UTC()) + dur!"msecs"(milliseconds)
```

Seems to work.
