Function std.datetime.systime.SysTime.toString
Converts this SysTime to a string.
string toString() nothrow scope @safe const;
void toString(W)
(
ref W writer
) const scope
if (isOutputRange!(W, char));
This function exists to make it easy to convert a SysTime to a
string for code that does not care what the exact format is - just that
it presents the information in a clear manner. It also makes it easy to
simply convert a SysTime to a string when using functions such
as to!string, format, or writeln which use toString to convert
user-defined types. So, it is unlikely that much code will call
toString directly.
The format of the string is purposefully unspecified, and code that
cares about the format of the string should use toISOString,
toISOExtString, toSimpleString, or some other custom formatting
function that explicitly generates the format that the code needs. The
reason is that the code is then clear about what format it's using,
making it less error-prone to maintain the code and interact with other
software that consumes the generated strings. It's for this same reason
that SysTime has no fromString function, whereas it does have
fromISOString, fromISOExtString, and fromSimpleString.
The format returned by toString may or may not change in the future.
