SysTime.this

this(DateTime dateTime, return scope immutable TimeZone tz = null) return scope @safe nothrow

Parameters

`dateTime`	The `DateTime` to use to set this SysTime's internal std time. As `DateTime` has no concept of time zone, tz is used as its time zone.
`tz`	The `TimeZone` to use for this SysTime. If null, `LocalTime` will be used. The given `DateTime` is assumed to be in the given time zone.

this(DateTime dateTime, Duration fracSecs, return scope immutable TimeZone tz = null) return scope @safe

Parameters

`dateTime`	The `DateTime` to use to set this SysTime's internal std time. As `DateTime` has no concept of time zone, tz is used as its time zone.
`fracSecs`	The fractional seconds portion of the time.
`tz`	The `TimeZone` to use for this SysTime. If null, `LocalTime` will be used. The given `DateTime` is assumed to be in the given time zone.

Throws

DateTimeException if fracSecs is negative or if it's

greater than or equal to one second.

this(Date date, return scope immutable TimeZone tz = null) return scope @safe nothrow

Parameters

`date`	The `Date` to use to set this SysTime's internal std time. As `Date` has no concept of time zone, tz is used as its time zone.
`tz`	The `TimeZone` to use for this SysTime. If null, `LocalTime` will be used. The given `Date` is assumed to be in the given time zone.

this(long stdTime, return scope immutable TimeZone tz = null) return scope @safe pure nothrow

Note

Whereas the other constructors take in the given date/time, assume

that it's in the given time zone, and convert it to hnsecs in UTC since midnight, January 1st, 1 A.D. UTC - i.e. std time - this constructor takes a std time, which is specifically already in UTC, so no conversion takes place. Of course, the various getter properties and functions will use the given time zone's conversion function to convert the results to that time zone, but no conversion of the arguments to this constructor takes place.

Parameters

`stdTime`	The number of hnsecs since midnight, January 1st, 1 A.D. UTC.
`tz`	The `TimeZone` to use for this SysTime. If null, `LocalTime` will be used.
