digitalmars.D.learn - Get date at compile time

Hi,

Is there any way to get the system date at compile time. I want 
something like:

static string compileDate = Clock.currTime.toString;

but that fails.

Thanks very much

Not exactly, but the special symbol __TIMESTAMP__ gets a string out of the compiler at build time. http://dlang.org/spec/lex.html#specialtokens

Has there been consideration for adding separate integral tokens for day, month, year, etc? The documentation there doesn't seem to specify but I assume currently the timestamps are for local time? Though I don't currently have any need for this feature I'd imagine that if I did I'd want the time in UTC, not locally, or if it was local that I'd at least want to be able to similarly retrieve the timezone info.

Not that I'm aware of. The purpose of this is more for things like version and help strings (e.g. "MyApp built 1 Oct 2016") than for serious processing, but you can also slice the string up to do more with it.

I think it would be better to implement a parse function for std.datetime which works at compile time. We need a parse function anyway. -- /Jacob Carlborg

You may invoke the compiler with TZ= prepended. (Linux)
