Unfortunately, there isn’t a an overload of Sum that accepts an IEnumerable<TimeSpan>. Additionally, there’s no current way of specifying operator-based generic constraints for type-parameters, so even though TimeSpan is “natively” summable, that fact can’t be picked up easily by generic code. One option would be to, as you say, sum up an integral-type equivalent to … Read more
You can use the Calendar class in order to check. For example: try { String string1 = “20:11:13”; Date time1 = new SimpleDateFormat(“HH:mm:ss”).parse(string1); Calendar calendar1 = Calendar.getInstance(); calendar1.setTime(time1); calendar1.add(Calendar.DATE, 1); String string2 = “14:49:00”; Date time2 = new SimpleDateFormat(“HH:mm:ss”).parse(string2); Calendar calendar2 = Calendar.getInstance(); calendar2.setTime(time2); calendar2.add(Calendar.DATE, 1); String someRandomTime = “01:00:00”; Date d = new SimpleDateFormat(“HH:mm:ss”).parse(someRandomTime); … Read more
DateTime.Ticks will account for the time. Use .Ticks on the DateTime to convert your dates into longs. Then just use a simple if stmt to see if your target date falls between. // Assuming you know d2 > d1 if (targetDt.Ticks > d1.Ticks && targetDt.Ticks < d2.Ticks) { // targetDt is in between d1 and … Read more
Environment.TickCount is based on GetTickCount() WinAPI function. It’s in milliseconds But the actual precision of it is about 15.6 ms. So you can’t measure shorter time intervals (or you’ll get 0) Note: The returned value is Int32, so this counter rolls over each ~49.7 days. You shouldn’t use it to measure such long intervals. DateTime.Ticks … Read more
Simple: Milliseconds are the remaining milliseconds, that don’t form a whole second. TotalMilliseconds is the complete duration of the timespan expressed as milliseconds.
Mongoose 3.x is complaining about the [] parameter in your findOne calls as the array format is no longer supported for the parameter that selects the fields to include. Try this instead to find the newest: Tweet.findOne({}, {}, { sort: { ‘created_at’ : -1 } }, function(err, post) { console.log( post ); }); Change the … Read more
You can use TimeSpan class, something like this: TimeSpan t = TimeSpan.FromMilliseconds(ms); string answer = string.Format(“{0:D2}h:{1:D2}m:{2:D2}s:{3:D3}ms”, t.Hours, t.Minutes, t.Seconds, t.Milliseconds); It’s quite similar as this thread I’ve just found: What is the best way to convert seconds into (Hour:Minutes:Seconds:Milliseconds) time?
It is not very logical to convert TimeSpan to DateTime. Try to understand what leppie said above. TimeSpan is a duration say 6 Days 5 Hours 40 minutes. It is not a Date. If I say 6 Days; Can you deduce a Date from it? The answer is NO unless you have a REFERENCE Date. … Read more
From this article TimeSpan duration = TimeSpan.FromMinutes(1); duration = TimeSpan.FromTicks(duration.Ticks * 12); Console.WriteLine(duration);
TimeSpan.FromTicks(28000000000).TotalMinutes;
