Colon in date format between seconds and milliseconds. How to parse in R?

由 风流意气都作罢 提交于 2019-12-08 16:10:08
问题 How can I parse this date format? Should I change this colon to dot or maybe someone know better solution? > x <- "2012.01.15 09:00:02:002" > strptime(x, "%Y.%m.%d %H:%M:%S:%OS") [1] "2012-01-15 09:00:02" > strptime(x, "%Y.%m.%d %H:%M:%OS") [1] "2012-01-15 09:00:02" > x <- "2012.01.15 09:00:02.002" > strptime(x, "%Y.%m.%d %H:%M:%OS") [1] "2012-01-15 09:00:02.001" 回答1: There's a subtle distinction here that may be throwing you off. As ?strptime notes: for 'strptime' '%OS' will input seconds

Getting millisecond format

问题 I am trying to get this string to return Minute:Second:Millisecond for my MediaPlayer. I have found this code, but can't figure out how to make the Milliseconds work and put it at 2 decimal places. I'm sure its simple to the right person! private String getTimeString(long millis) { StringBuffer buf = new StringBuffer(); int hours = (int) (millis / (1000*60*60)); int minutes = (int) (( millis % (1000*60*60) ) / (1000*60)); int seconds = (int) (( ( millis % (1000*60*60) ) % (1000*60) ) / 1000);

Delphi - How to make timer in milliseconds or nanoseconds with start/stop functions?

由 北战南征 提交于 2019-12-07 17:26:44
问题 I am looking for a timer in milliseconds or nanoseconds in Delphi7. I have to check the speeds of three ISAM files with sequential search. The first ind file contains 50 strings like "record_0" to "record_50". The second - "record_0" to "record_500" and the third - "record_0" to "record_5000". I've implemented everything but I don't know how to make the timer. I am comparing a string with the last item in each ISAM file. Here is my code for the first ind file: procedure TForm1.Button1Click

Python logging: override log time

由 我与影子孤独终老i 提交于 2019-12-07 08:27:22
问题 Following Python's documentation, I'm trying to override logging.Formatter.converter in order to control the time logged. As you can see below - the milliseconds were not overriden (they are the current time milliseconds). How come? How can I control the milliseconds as well? >>> import logging, datetime >>> formatter = logging.Formatter('%(asctime)s:%(message)s') >>> handler = logging.StreamHandler() >>> handler.setFormatter(formatter) >>> def sim_time(t): ... return datetime.datetime(2000,1

Getting current date in milliseconds (UTC) (NO use of strings)

由 回眸只為那壹抹淺笑 提交于 2019-12-05 14:13:35
问题 Well, you might think that this question has already been asked, but I think it has not. The solutions I've read about all had this "jigsaw puzzle" technique (like getUTCMonth() + getUTCMinutes + ... ). But as I only want to compare the elapsed seconds between two UTC (!) dates, this does not apply. As everybody knows, you can get the current (non-UTC) date by: var d = new Date(); var t_millis = d.getTime(); But this is NOT what I want. I'd like to have the current system date in UTC and in

Python Pandas custom time format in Excel output

由 ぐ巨炮叔叔 提交于 2019-12-05 02:31:47
问题 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

How can I get the count of milliseconds since midnight for the current?

由 ℡╲_俬逩灬. 提交于 2019-12-04 07:35:47
问题 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. 回答1: Do you mean? long millis = System

Convert Date to Milliseconds in MySQL

由 ε祈祈猫儿з 提交于 2019-12-04 03:12:34
I am trying to convert a date in MySQL to milliseconds . This is what I have to get the date: DATE_ADD(mydate, INTERVAL(1-DAYOFWEEK(mydate)) DAY) But that returns me like 15/02/2015 and I want to get the milliseconds of that date. Use the UNIX_TIMESTAMP function. SELECT (UNIX_TIMESTAMP(mydate)*1000) FROM... UNIX_TIMESTAMP will get you seconds and you need to multiply by 1000 to get milliseconds. To convert back, use FROM_UNIXTIME() function. SELECT FROM_UNIXTIME(date_in_milliseconds/1000) FROM ... Again, you need to divide by 1000 to get it to seconds before using the function. 来源： https:/

How to write bigint (timestamp in milliseconds) value as timestamp in postgresql

由 流过昼夜 提交于 2019-12-04 00:14:07
I'm trying to store in timestamp with timezone field my value. It is in milliseconds from 1970. select TO_CHAR(TO_TIMESTAMP(1401432881230), 'DD/MM/YYYY HH24:MI:SS.MS') Expected 30/5/2014 11:29:42 10:54:41.230 , but get 22/08/46379 23:27:02.000 Unix timestamps measures time with seconds, and not milliseconds ( almost everywhere, in PostgreSQL too). Therefore you need to call SELECT TO_TIMESTAMP(1401432881230 / 1000); If you want to preserve milliseconds, call with double precision : SELECT TO_TIMESTAMP(1401432881230::double precision / 1000); This is how I convert ms to timestamp and keep ms
