Extract Timestamp from ULID

See more ULID/UUID Examples

Extract the date/time from a ULID.

Important: Chilkat's ULID functionality was introduced in v9.5.0.94.

Zig

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

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

    const ulid = "01GRH14AA82EY9A7S99YYF2QDY";

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

    // Unix timestamps stored in ULIDs should be UTC...
    const b_local = false;
    // Set the CkDateTime from the timestamp contained in the ULID
    dt.setFromUlid(b_local, ulid) catch {
        std.debug.print("ULID was not valid.\n", .{});
        return;
    };

    // You can now get the date/time in any desired format.
    // For example:
    std.debug.print("Unix timestamp = {d}\n", .{dt.getAsUnixTime(b_local)});
    std.debug.print("RFC822 = {s}\n", .{try dt.getAsRfc822(alloc, b_local)});
    std.debug.print("Timestamp = {s}\n", .{try dt.getAsTimestamp(alloc, b_local)});

    // Sample output:

    // Unix timestamp = 1675608861
    // RFC822 = Sun, 05 Feb 2023 14:54:21 GMT
    // Timestamp = 2023-02-05T14:54:21Z
