Examples:
Get the current time from the system clock
import std.datetime.systime : SysTime, Clock; SysTime currentTime = Clock.currTime();
Examples:
Construct a specific point in time without timezone information
and get its ISO string.
import std.datetime.date : DateTime; auto dt = DateTime(2018, 1, 1, 12, 30, 10); writeln(dt.toISOString()); // "20180101T123010" writeln(dt.toISOExtString()); // "2018-01-01T12:30:10"
Examples:
Construct a specific point in time in the UTC timezone and
add two days.
import std.datetime.systime : SysTime; import std.datetime.timezone : UTC; import core.time : days; auto st = SysTime(DateTime(2018, 1, 1, 12, 30, 10), UTC()); writeln(st.toISOExtString()); // "2018-01-01T12:30:10Z" st += 2.days; writeln(st.toISOExtString()); // "2018-01-03T12:30:10Z"
