A naive UUID V4 compliant timestamp uuid with millisecond precision, for which also the string representation is correctly sorted by encoded timestamp. Please don't confuse it with time uuids used by e.g. cassandra where the string representation is not sortable by timestamp. The timestamp occupies 56 bit, such that it roughly works for the next 2 million years (from year 2022 on) with millisecond precision.
Install the gem and add to the application's Gemfile by executing:
$ bundle add timestamp_uuid
If bundler is not being used to manage dependencies, install the gem by executing:
$ gem install timestamp_uuid
To generate timestamp uuids:
TimestampUuid.generate
# => "00018a07-fb46-4bb0-0001-45c4003779fd"
TimestampUuid.generate(Time.parse("2023-08-12 12:00:00 CEST"))
# => "000189e9-303d-4000-0003-625c21b0936b"
To parse and instantiate timestamp uuids:
TimestampUuid.new("000189e9-303d-4000-0003-625c21b0936b")
=> #<TimestampUuid:0x00007f06d2f5a020 @sequence_number=3, @timestamp=2023-08-12 12:00:00 +0200, @uuid="000189e9-303d-4000-0003-625c21b0936b", @version=4>
That's it!
