Dim dt As ChilkatDateTime
dt.Initialize

'  Set dt to the current system date/time.
dt.SetFromCurrentSystemTime

'  Generate a ULID for the current UTC date/time.
'  (i.e. the current UTC UNIX-time)
Dim utc As Boolean = True
Dim ulid As String = dt.UlidGenerate(utc)
Log(ulid)

'  example result: 01GRGCH4J88RECEN4D4VK4F629

'  Generate a ULID using the local timezone's current time.
utc = False
ulid = dt.UlidGenerate(utc)
Log(ulid)
