Zig Datetime

A datetime module for Zig with an api similar to python's Arrow.

NOTE DST is now implemeted to the library. Some timezones that relying on islamic calendar for DST might not work yet. It is also possible that we might have skipped some timezones by mistake because there are a lot of timezones.

IMPORTANT With DST implementation, the shiftTimezone method changed and now taking timezone argument passed by value contrary to before that it was passed by pointer.

Install

1. Add zig-datetime as a dependency in your build.zig.zon:

zig fetch --save git+https://github.com/frmdstryr/zig-datetime#master

1. In your build.zig, add the datetime module as a dependency you your program:

const pg = b.dependency("datetime", .{
    .target = target,
    .optimize = optimize,
});

// the executable from your call to exe_mod.addExecutable
exe.root_module.addImport("datetime", pg.module("datetime"));

Example

const allocator = std.heap.page_allocator;
const date = try Date.create(2019, 12, 25);
const next_year = date.shiftDays(7);
assert(next_year.year == 2020);
assert(next_year.month == 1);
assert(next_year.day == 1);

// In UTC
const now = Datetime.now();
const now_str = try now.formatHttp(allocator);
defer allocator.free(now_str);
std.debug.warn("The time is now: {}\n", .{now_str});
// The time is now: Fri, 20 Dec 2019 22:03:02 UTC
