Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const date_time = try chilkat.DateTime.init();
    defer date_time.deinit();

    date_time.setFromCurrentSystemTime() catch {};

    std.debug.print("Current time: {s}\n", .{try date_time.getAsTimestamp(alloc, false)});

    date_time.addSeconds(1) catch {};
    std.debug.print("Current time + 1 second: {s}\n", .{try date_time.getAsTimestamp(alloc, false)});

    date_time.addSeconds(-2) catch {};
    std.debug.print("Current time - 1 second: {s}\n", .{try date_time.getAsTimestamp(alloc, false)});

    // Add 30 days (60 * 60 * 24 * 30)
    date_time.addSeconds(60 * 60 * 24 * 30) catch {};
    std.debug.print("Current time + 30 days: {s}\n", .{try date_time.getAsTimestamp(alloc, false)});

    // Sample output for test run on 2-Dec-2016:

    //     Current time: 2016-12-02T12:59:13Z
    //     Current time + 1 second: 2016-12-02T12:59:14Z
    //     Current time - 1 second: 2016-12-02T12:59:12Z
    //     Current time + 30 days: 2017-01-01T12:59:12Z
