Thought I would let everyone know that while std.dateparse is deprecated and will be removed from Phobos in February, I've updated it to output a std.datetime.SysTime.

https://gist.github.com/1283011

I don't have any interest in maintaining it, but since I did use it I updated it for me.

Time formatting and parsing seems like a gap of missing functionality in Phobos 2.

I've written something to format and parse SysTimes using format strings based on the format PHP uses for its date() function:
https://github.com/CyberShadow/ae/blob/master/utils/time.d

Feel free to use this file as public domain.

It formats and parses specific, official formats just fine, but it doesn't currently support user-defined formats. It's on my TODO list. Eventually, there will be something along the lines of toCustomString and fromCustomString on Date, TimeOfDay, DateTime, and SysTime, where they take a format string defining the custom format.

For my use dateparse was actually want I wanted. I was pulling out strings saying, "Hey this looks like it might be a date, what do you think?" "Yeah, cool thank you." I don't wish to try and push it back into Phobos but thought others may well still be interested as I was.

That's fine. Vladimir was saying that std.datetime's formatting and parsing abilities left something to be desired, so I was pointing out that I do intend to give it the ability to handle custom formats. It's not really my intention at this point that std.datetime gain the ability to take a string representing a date and/or time in an unknown format. There's obviously no problem with you making such code available for those who might want it though.

Yes, me too. I used to get tremendously frustrated with the old std.date, because all I wanted to do was get the current time and write it into a log file!

Are you sure you're worthy? :-)

My library includes a date/time formatting facility that's much better than PHP's.

http://pr.stewartsplace.org.uk/d/sutil/

Spec of the format string scheme:
http://pr.stewartsplace.org.uk/d/sutil/datetime_format.html

Walter - when the time comes to implement custom date/time formatting, will you consider using my scheme?

What does Walter have to do with anything here? He's not implementing any date/time stuff, and he's not all that involved with Phobos development in general. I'm likely the one to be implementing the custom date/time formatting, and the current plan is to do something similar to strftime, since that scheme seems to be fairly standard across several languages.

The locale detection is broken, as this example shows.

----- dateparse_test.d -----
import dateparse, std.cstream, std.datetime;

void main() {
	string s;
	while ((s = din.readLine().idup) != "") {
		SysTime t;
		dateParse(s, t);
		dout.writefln("%s", t);
	}
}
