milliseconds

I have used pandas.groupby to group a pandas DataFrame on two columns and calculate average and median times. My resulting dataset looks similar to this: Size Category Average Time Median Time 1 A 0.002056385 0.000310995 B 0.000310995 C 0.000310995 10 A 0.001852681 B 0.000310995 C 0.000310995 I would like to export this table to excel and format the Time Columns as a custom format in Excel like so (hh:mm:ss.000). In other words, I want to view the times as millisecond-level times. For example, 0.000310995 formatted in this fashion displays as 00:00:26.870 (26.870 seconds). Does anyone have any

I've been venturing down the odyssey of trying to get fractional time resolution working properly in my database. I use the python method datetime.now() in order to create date objects. I then store these objects in a field which is mapped to a COLUMN(DATETIME(9)) which is from SqlAlchemy's library. Originally, I was getting an error that my data was being truncated. This is because I was using mysql 5.5. I have since updated to 5.6.19 and no longer get the data truncated error. However, the database still does not actually contain fractional time entries. For example, here is the value from

Note, I do NOT want millis from epoch. I want the number of milliseconds currently on the clock. So for example, I have this bit of code. Date date2 = new Date(); Long time2 = (long) (((((date2.getHours() * 60) + date2.getMinutes())* 60 ) + date2.getSeconds()) * 1000); Is there a way to get milliseconds with date? Is there another way to do this? Note: System.currentTimeMillis() gives me millis from epoch which is not what I'm looking for. Do you mean? long millis = System.currentTimeMillis() % 1000; BTW Windows doesn't allow timetravel to 1969 C:\> date Enter the new date: (dd-mm-yy) 2/8/1969

Soundcloud's API gives the duration of it's tracks as milliseconds. JSON looks like this: "duration": 298999 I've tried many functions I found on here to no avail. I'm just looking for something to convert that number to something like looks like this: 4:59 Here's one that got close, but doesn't work. It doesn't stop the seconds at 60. It goes all the way to 99 which makes no sense. Try entering "187810" as a value of ms, for example. var ms = 298999, min = Math.floor((ms/1000/60) << 0), sec = Math.floor((ms/1000) % 60); console.log(min + ':' + sec); Thanks for your help! If you could add in

I'm making a program in which I need to get the time in milliseconds. By time, I mean a number that is never equal to itself, and is always 1000 numbers bigger than it was a second ago. I've tried converting DateTime.Now to a TimeSpan and getting the TotalMilliseconds from that... but I've heard it isn't perfectly accurate. Is there an easier way to do this? Use the Stopwatch class. Provides a set of methods and properties that you can use to accurately measure elapsed time. There is some good info on implementing it here: Performance Tests: Precise Run Time Measurements with System

i have this code, i need show only hours:min:sec, any help? String var = "1429174464829"; (this is time in System.currentTimeMillis() ) String p = "HH:mm:ss"; SimpleDateFormat f = new SimpleDateFormat(p); long t = var - System.currentTimeMillis(); String result = f.format(new Date(t)); in example String var, is 1 hours higher than System.currentTimeMillis() result problem EDIT: i obtain: result = 21:59:00 thanks Java 8 Okay, this is a little unpleasant, but will get the job done, this is using Java 8's Time API LocalDateTime dt1 = LocalDateTime.ofInstant(Instant.ofEpochMilli(1429174464829L),

This question already has an answer here: Java - Subtract Days from date [duplicate] 6 answers I am trying to do something really simple. I am trying to subtract 2 days from the current day. I get the number of hours from the UI. So in this example, I get 48 hours from the UI. I am doing the following and I don't know what i'm doing wrong here. I think the result of this is it only subtracts a few minutes from the time. long timeInEpoch = (currentMillis()/1000 - (48 * 60 * 60)); //48 comes from UI public long currentMillis(){ return new Date().getTime(); } d = new Date(timeInEpoch * 1000); I
