Hi,

I have a program that uses the old time stuff before the module std.datetime. I have a DateTime object, but I can't seem to set its properties to the current time.

Some thing like:
DateTime dateTime;
dateTime = getCurrentDateTime();

May I suggest that you put an example on top of that article that gets the current date and time.

It's already in the documentation at the top of the module. What I need to do is put a link to the article in that documetantion.

I just added a link to the article to std.datetime, so it'll be there starting with the next release. What I'd _really_ like to see fixed though is the anchor-generation with ddoc so that I can actually properly organize the links at the top of std.datetime.

Thanks Jonathan, that helped I think, (haven't read it all, though). But I've got errors with some of the date times not being able to change them with int's values.

task.d(44): Error: function std.datetime.DateTime.month () const is not callable using argument types (int)
task.d(44): Error: cannot implicitly convert expression (month0) of type int to Month

That would be nice too.

Month is an enum. So, any function taking a month must take an enum value, not an integer. e.g. Month.jan, Month.feb, Month.mar, etc. If you want to pass it an integral value, you have to cast. e.g. cast(Month)1, cast(Month)2, cast(Month)3, etc.

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);
