I was wondering the same thing myself. I could not find anything in Base.
Here is something that works, at least in Julia 0.4, based on
base/reflection.jl:functionloc()
Use it with: `macroloc(:@time)`
function macroloc(expr::Expr)
@assert expr.head == :macrocall
f=getfield(current_module(),expr.args[1])
lsd = f.code::LambdaStaticData
ln = lsd.line
if ln <= 0
error("could not determine location of macro definition")
end
(Base.find_source_file(string(lsd.file)), ln)
end
