granularity in the Datatime column #66

Closed KimballCai closed 2 years ago

KimballCai commented 2 years ago

The COOL stores and compresses the DateTime column by the int values. Hence, it can only process the time step by day. If we update the storage into float type, it can process the time step by an hour, a minute, and even a second.

We have updated the code, and COOL can process the data by days, months, and years in the PR https://github.com/COOL-cohort/COOL/pull/54
