Add time.Time type support to where tpl func

Browse source 
`where` tpl function doesn't support `time.Time` type so if people want
to compare such values, it's required that these values are converted
into `int` and compare them.

This improves it. If `time.Time` values are passed to `where`, it
converts them into `int` internally, compares them and returns the
result.
