Description

The test TestGCSIO.test_last_updated uses timestamp 123456.78 as the last updated timestamp.  This timestamp is converted into a naive datetime in the Fakefile class get_metadata method (gcsio_test.py line 72) Then in the GcsIO class last_updated method (gcsio.py ) is converted back to timestamp. But the conversion is incorrect when the the timezone offset is different in 1970 and now. In my case now Singapore is GMT+8 and it was only GMT+7:30 in 1970. So the test fails.
