It has been reported here that if one writes a sav file with variables with format DATE and DATETIME, those are not read correctly in PSPP (read as plain numbers) with some error messages about wrong print format. Interestingly TIME is is read correctly.

However the same file is read correctly in SPSS and the variables are formatted as expected.

At a first glance this looks to me like an issue in PSPP, however if I understood correctly both PSPP and Readstat use the same file specification (this one?) and therefore I would assume that what Readstat writes should be compatible with PSPP?

What's your opinion on the topic?
