See more ULID/UUID Examples

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

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

ulid = "01GRH14AA82EY9A7S99YYF2QDY"

dt = Chilkat::CkDateTime.new()

# Unix timestamps stored in ULIDs should be UTC...
bLocal = false
# Set the CkDateTime from the timestamp contained in the ULID
success = dt.SetFromUlid(bLocal,ulid)
if (success == false)
    print "ULID was not valid." + "\n";
    exit
end

# You can now get the date/time in any desired format.
# For example:
print "Unix timestamp = " + dt.GetAsUnixTime(bLocal).to_s() + "\n";
print "RFC822 = " + dt.getAsRfc822(bLocal) + "\n";
print "Timestamp = " + dt.getAsTimestamp(bLocal) + "\n";

# Sample output:

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