[ruby-core:66494] [ruby-trunk - Feature #10544] Time#to_i(:millisecond)

Issue #10544 has been updated by David MacMahon.


How about a more general `Time#to_i(scale=1)`?

Examples:

* Passing `1` for `scale` (or passing nothing) would return seconds.
* Passing `1000` for `scale` would return milliseconds.
* Passing `1/60r` for scale would return minutes.

IMHO, it is generally preferable to avoid time travel by truncating to the beginning of the "present" millisecond rather than possibly rounding to the beginning of the "future" millisecond.

Currently, we have to take an indirect way to get unix_time in milliseconds.

~~~ruby
time = Time.now
milliseconds = (time.to_i * 1000) + (time.usec / 1000.0).round
~~~

I think it would be convenient if `Time#to_i` accepts unit parameter like following.

~~~ruby
time = Time.now
milliseconds = time.to_i(:millisecond)
~~~
