Lua Requires Chilkat v9.5.0.94+

Generate ULID

See more ULID/UUID Examples

Generate a ULID using a specified timestamp or the current system date timestamp. Lua

local chilkat = require("chilkat")

local dt = chilkat.DateTime.new()

-- Set dt to the current system date/time.
dt:set_from_current_system_time()

-- Generate a ULID for the current UTC date/time.
-- (i.e. the current UTC UNIX-time)
local utc = true
local ulid = dt:ulid_generate(utc)
print(ulid)

-- example result: 01GRGCH4J88RECEN4D4VK4F629

-- Generate a ULID using the local timezone's current time.
utc = false
ulid = dt:ulid_generate(utc)
print(ulid)

-- example result: 01GRH14AA82EY9A7S99YYF2QDY

-- To generate a ULID using a specific UNIX timestamp

-- For example, the Unix timestamp for Sun, 05 Feb 2023 14:57:46 GMT
-- is 1675609066

-- For more information about the Epoch Unix Timestamp, see Epoch Unix Timestamp

-- To generate a ULID from a specified date/time, set the CkDateTime and then generate the ULID.
local dt2 = chilkat.DateTime.new()
utc = true
dt2:set_from_unix_time(utc, 1675609066)
ulid = dt2:ulid_generate(utc)
print(ulid)
