time

问题 I am trying to parse my date string with time library. But i have an error in parsing. # Example is 'In 0 days 23:07:56' client['license_time_start'] = time.strptime('In 0 days 23:07:56', 'In %d days %H:%M:%S') ValueError: time data 'In 00 days 23:07:56' does not match format 'In %d days %H:%M:%S' 回答1: The error is because date can't be 0 . It has to be an positive integer. Therefore, this produces an error:- time.strptime('In 0 days 23:07:56', 'In %d days %H:%M:%S') # ValueError: time data

问题 The data in my Excel files is supposed to be contentious (index in the first column). But some data is missing in the file. For example, # 5, and 6 are missing between $ 4 and 7. My purpose are (1) identify the file with missing data and (2) if data is missing insert rows to make it continuous. Can anyone tell me how to add in rows in the existing data? Using xlswrite I can only add in rows at the end of the file or replace some rows. EDIT 1: I have another set of file in which the index is

问题 I've been searching for an answer to my dilemma and have found some useful tips but nothing that addresses my specific question, so I was hoping someone here might be able to help me out. I'm trying to get a precise elapsed time to the millisecond in Java. I'm using System.nanoTime() to get the current time and implementing it in the following code. Mind you, this was code that I used to test it's precision. long startTime = System.nanoTime()/1000000; while (true) { System.out.println((System

问题 I have a data frame of character times that I need to average by provider, but I'm not sure how to average them using just the time without the date. For the example below: provider time USA 9:26:46 USDA 9:26:18 USDA 9:10:17 OIL 10:00:00 USA 6:20:56 USDA 7:19:13 OIL 11:00:00 The correct output for OIL would be the average between 10:00 and 11:00, and would look like: provider average OIL 10:30 Does anyone know how to average just time without incorporating date using POSIX? 回答1: mean works as

问题 I don't know what's happening here: I need to return true if the current time is between a given range, ex: now is 15:45:00 and is between 12:00:00(min) and 18:00:00(max), but this method is doing it wrong: private boolean verifyIfInside(String max, String min){ try { DateFormat dateFormat = new SimpleDateFormat ("HH:mm:ss"); Date date = new Date(); String hour1 = min; String hour2 = max; String newHour = dateFormat.format(date); Date minHour, maxHour, nowHour; minHour = dateFormat.parse

问题 I'm using Java's default TimeZone and Calendar classes to try and get the time of different areas, however when I try to use it, it doesn't take into account any +0x:00. For example when I enter "Europe/England" it returns me 1:30, when it's actually 2:30 since right now England is using GMT+1, not GMT. String timeZone = raw.split(" ")[1]; Calendar calendar = new GregorianCalendar(); TimeZone tz; try { tz = TimeZone.getTimeZone(timeZone); calendar.setTimeZone(tz); } catch (Exception e) {

问题 I am building pizza delivery website with WooCommerce. In fact when customer is checking out, he can select when he want to have food delivered. The select box should contain 15 minute intervals ranging from the current time and clearing all past hours.

Our delivery hours are as below: Monday: Closed Tuesday - Friday 11:30 - 14:00 & 17:00 -

问题 Even though it is good to check performance of code in terms of algorithmic analysis and Big-Oh! notation i wanted to see how much it takes for the code to execute in my PC. I had initialized a List to 9999count and removed even elements out from the them. Sadly the timespan to execute this seems to be 0:0:0 . Surprised by the result there must be something wrong in the way i time the execution. Could someone help me time the code correct? IList<int> source = new List<int>(100); for (int i =
