time.localtime

[Konstantin8105]

Add test and implementation on Go for function time.h localtime
Description: https://en.cppreference.com/w/c/chrono/localtime
File for test code add : c4go/tests/time.c
Example see #155

[Konstantin8105]

How to run test for that issue:

go test -v -tags=integration -run=TestIntegrationScripts/tests/time.c
go test -v -run=TestCSTD

[IngCr3at1on]

I was going to take a crack at this but it looks like the existing time tests fail which makes me skittish about adding anything.

@Konstantin8105 do you know why the above errors might be occuring?

[Konstantin8105]

@IngCr3at1on , tests is ok by travis and my local laptop. Now, darwin(MacOS) is not supported. Could you clarify:

• OS
• golang version
• clang version

[IngCr3at1on]

Sure; Arch Linux, go version go1.11 linux/amd64, clang version 7.0.0

[Konstantin8105]

It is look very nice.
Now, we use clang 6.0 for testing. May be is the problem.

c4go/.travis.yml

Line 34 in 44a79fa

- env: SCRIPT=test CLANG=6.0

May be you have some specific implementation of glibc.
