Error in num2date cinversion #981

Description

@rkouznetsov
#!/usr/bin/env python

import numpy as np
import netCDF4 as nc4
iarr=np.arange(86400, dtype=np.int32)
units='hours since 2018-01-01 00:00:00 UTC'
dates1 = nc4.num2date(iarr,units)[-5:]
dates2 = nc4.num2date(iarr[-5:],units)
print dates1 == dates2

Results in
[ True False True True False]
Should be
[ True True True True True]
as it used to be for me until recent update.

Environment:
Ubuntu 18.04, python-numpy 1:1.13.3-2ubuntu1, python-netcdf4 1.3.1-1

Actually, result is the same for iarr dtype of float32, float64, or int64.

Thank you!
