Content
A similar issue was resolved with issue29097 (with 0 <= t <= 86399). Here, we have an inconsistency between OSes when using datetime.fromtimestamp(t) when t < 0. Tested on Python 3.6.7. GNU/Linux: >>> datetime.fromtimestamp(-1) datetime.datetime(1970, 1, 1, 0, 59, 59) macOS: >>> datetime.fromtimestamp(-1) datetime.datetime(1970, 1, 1, 0, 59, 59) Windows (7 and 10): >>> datetime.fromtimestamp(-1) Traceback (most recent call last): File "<stdin>", line 1, in <module> OSError: [Errno 22] Invalid argument I think having a similar behavior between all Oses would be great, right?
