Feature #10544
closed
Added by Glass_saga (Masaki Matsushita) over 9 years ago.
Updated almost 8 years ago.
Description
Currently, we have to take an indirect way to get unix_time in milliseconds.
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.
time = Time.now
milliseconds = time.to_i(:millisecond)

- Description updated (diff)
Do you need unix time in milliseconds so often?
I want this feature to give unix time to other languages like JavaScript.
Some languages expect unix time in milliseconds.
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.
- Status changed from Open to Rejected
We have Process.clock_gettime since Ruby 2.1.
% ruby -e 'p Process.clock_gettime(Process::CLOCK_REALTIME, :millisecond)'
1478362786099
This can be used as Time.now.to_i(:millisecond) which is shown in this issue.
If it is not enough, please reopen.
