Demonstrates the how to tell if a date/time is older than the current time by N seconds, minutes, hours, or days. Zig

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

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

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

    // Set to the current system date/time.
    dt.setFromCurrentSystemTime() catch {};
    std.debug.print("Now: {s}\n", .{try dt.getAsTimestamp(alloc, true)});

    // Subtract 10 minutes, making the date 10 minutes in the past.
    dt.addSeconds(-600) catch {};
    std.debug.print("10 minutes ago: {s}\n", .{try dt.getAsTimestamp(alloc, true)});

    // Is the date/time older than 10 seconds?
    var b: bool = dt.olderThan(10, "seconds");
    std.debug.print("Older than 10 seconds: {}\n", .{b});

    // Is the date/time older than 5 minutes?
    b = dt.olderThan(5, "minutes");

    // Is the date/time older than 15 minutes?
    b = dt.olderThan(15, "minutes");
    std.debug.print("Older than 15 minutes: {}\n", .{b});

    // Is the date/time older than 1 hour?
    b = dt.olderThan(1, "hour");
    std.debug.print("Older than 1 hour: {}\n", .{b});

    // Is the date/time older than 1 day?

    // Output:

    //     Now: 2017-05-05T23:33:06-0500
    //     10 minutes ago: 2017-05-05T23:23:06-0500
    //     Older than 10 seconds: True
    //     Older than 5 minutes: True
    //     Older than 15 minutes: False
    //     Older than 1 hour: False
    //     Older than 1 day: False
