Why is it so hard to simply get the current date and time 
formatted properly in a string?

There are no examples of this in your documentation yet this 
is probably one of the most used cases.

To get the current time, use Clock.currTime. It will return the 
current time as a SysTime. To print it, toString is sufficient, 
but if using toISOString, toISOExtString, or toSimpleString, 
use the corresponding fromISOString, fromISOExtString, or 
fromSimpleString to create a SysTime from the string.

auto currentTime = Clock.currTime();
auto timeString = currentTime.toISOExtString();
auto restoredTime = SysTime.fromISOExtString(timeString);

This is what I use:

        auto getDateTimeString() {
                import std.string;
                import std.datetime;
                
                DateTime dateTime = cast(DateTime)Clock.currTime();
                with(dateTime)
                {
                        return format(
                                "%s " // day of the week (eg. 'Saturday')
                                "%s.%02s.%s " // date, month, year
                                "[%s:%02s:%02s%s]", // hour:minute:second am/pm
				split("Sunday Monday Tuesday Wednesday Thursday Friday 
Saturday")[dayOfWeek],
                                day, cast(int)month, year,
				hour == 0 || hour == 12 ? 12 : hour % 12, minute, second, 
hour <= 11 ? "am" : "pm");
                }
        }
