Need to conserder the precision problem among time and storage. #146

Open KimballCai opened 1 year ago

KimballCai commented 1 year ago

If we use int32 to store the time(i.e., the time interval), we can only analyze 68 years because of the INT32 ranges in [-2147483648, 2147483647].

For more details, please check the problem YEAR2038.

Next, we need to support int64 storage format.
