duration

Hi I'm trying to calculate the difference (duration) between two times in Groovy. e.g. start = "2010-10-07T22:15:33.110+01:00" stop = "2010-10-07T22:19:52.356+01:00" Ideally I would like the get the duration returned in Hours, Minutes, Seconds, Milliseconds. Can anybody please help. I've tried to use Groovy's duration classes but have not been able to make any progress. Thanks for your assistance. If you just want to find the difference between two times you create yourself (for instance to see how long something takes to execute) you could use: import groovy.time.* def timeStart = new Date()

I used to calculate the duration of MP3 files server-side using ffmpeg - which seemed to work fine. Today i discovered that some of the calculations were wrong. Somehow, for some reason, ffmpeg will miscalculate the duration and it seems to happen with variable bit rate mp3 files only. When testing this locally, i noticed that ffmpeg printed two extra lines in green. Command used: ffmpeg -i song_9747c077aef8.mp3 ffmpeg says: [mp3 @ 0x102052600] max_analyze_duration 5000000 reached at 5015510 [mp3 @ 0x102052600] Estimating duration from bitrate, this may be inaccurate After a nice, warm google

I have a potentially long-running test written with scalatest : test("a long running test") { failAfter(Span(60, Seconds)) { // ... } } Even if the test finishes within the timeout limit, its running time can be valuable to the person who runs the test. How can I measure and display the running time of this single particular test in scalatest's output? Update: Currently I measure the running time with my own function, just as in r.v's answer. I'd like to know if scalatest offers this functionality already. the -oD option will give the duration of the test. For example, I use the following in

I'm looking for the best way to use a duration field in a Rails model. I would like the format to be HH:MM:SS (ex: 01:30:23). The database in use is sqlite locally and Postgres in production. I would also like to work with this field so I can take a look at all of the objects in the field and come up with the total time of all objects in that model and end up with something like: 30 records totaling 45 hours, 25 minutes, and 34 seconds. So what would work best for? Field type for the migration Form field for the CRUD forms (hour, minute, second drop downs?) Least expensive method to generate

I would like to store the login, logout and duration time in database. The login time is created when the user is authenticated(successfully logged in) The logout time is created when the user clicks the logout button The duration is logout - login time. (logout minus login) But the problem is, what if the user didnt click the logout button. Here are the situations: Internet loss Close the browser/tab. (I need this must use javascript, but i donnu how to do it, any idea?) EDIT: I forgot to add something to the question, the program is a full flash program, there is no navigation to other page.
