One thing QB64 and its ancestors lacks, that VB6 and VBA and pretty much all modern languages have, is a native date/time type and associated operations and formatting functions. There are already 16 or so numeric types, so how about one for date/time?
I started throwing together some basic date/time functions, maybe someone will find this useful.
I'm sure this code could be done more efficiently but it seems to be working OK. There are still some features missing (a standard format date function, epoch-to-string function, count quarter/month/weekday/week, etc.) so this is still a Work in Progress.

'SUMMARY:

Dim Add2 As String
