relative-time-span

问题 I am using Groovy. I have parsed a textfile whose lines contain information, including dates. I now have just the dates, for example: 08:13:16,121 09:32:42,102 10:43:47,153 I want to compare the deltas between these values; how can I do this? i.e, I want to subtract the first from the second, and compare that value to the difference between the third and the second. I will save the largest value. 回答1: Assuming your times are in a file times.txt , you can do this: def parseDate = { str -> new

问题 In Ruby on Rails, there is a feature that allows you to take any Date and print out how \"long ago\" it was. For example: 8 minutes ago 8 hours ago 8 days ago 8 months ago 8 years ago Is there an easy way to do this in Java? 回答1: Take a look at the PrettyTime library.

It seems you're mostly thinking about getting the date into the '5 days ago' format, etc.. right? This is how I'd go about

问题 Given a specific DateTime value, how do I display relative time, like: 2 hours ago 3 days ago a month ago 回答1: Jeff, your code is nice but could be clearer with constants (as suggested in Code Complete). const int SECOND = 1; const int MINUTE = 60 * SECOND; const int HOUR = 60 * MINUTE; const int DAY = 24 * HOUR; const int MONTH = 30 * DAY; var ts = new TimeSpan(DateTime.UtcNow.Ticks - yourDate.Ticks); double delta = Math.Abs(ts.TotalSeconds); if (delta < 1 * MINUTE) return ts.Seconds == 1 ?
