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()); You can do `SysTime(unixTimeToStdTime(0))` to get a SysTime that is at the unix epoch. Also figured out the second question based on your result. Simply doing: ``` SysTime(DateTime(1970, 1, 1), UTC()) + dur!"msecs"(milliseconds) ``` Seems to work. Note there is an `msecs` function: ```d SysTime(unixTimeToStdTime(0)) + milliseconds.msecs; ``` https://dlang.org/phobos/std_datetime_systime.html#unixTimeToStdTime https://dlang.org/phobos/core_time.html#msecs -Steve

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
Re: Hide console on Windows with app running SDL2
