问题 I need to parse a date in the following format in my Flutter application (come from JSON) : 2019-05-17T15:03:22.472+0000 According to the documentation, I have to use Z to get the time zone (last 5 characters in RFC 822 format), so I use the following : new DateFormat("y-M-d'T'H:m:s.SZ").parseStrict(json['startDate']); But it fails with error : FormatException: Characters remaining after date parsing in 2019-05-17T15:03:22.472+0000 Here is another test : /// THIS WORKS try { print(new

问题 My question is basically the same as this one, but I'm not in a position to change the date format in the Excel file: If I format the cell as date english (NZ), ie Date Type "*14/03/2001", it displays right in the spreadsheet, but when I try to upload it switched the day and month. But If I change the format to a custom "dd/mm/yyyy" format [it works fine]. So the question is this: Can I change the way <cfspreadsheet /> handles date formats? Or even better, get a Date object directly from the

问题 The following code throws an " Out of bounds nanosecond timestamp: 1452-04-15 00:00:00 " error. The same code works if I replace the date strings to some recent dates such as 2017-01-01. df=pd.DataFrame({'Date':np.arange('1452-04-15', '1519-05-02', dtype='datetime64[D]')}) This example code is for providing an easy way to reproduce the error. What I am really trying to get done is to read a csv containing very early dates like these into a dataframe, and to convert the string dates into np

问题 I feel like there's a pretty simple way to do this, but I'm not finding it easily... I am working with R to extract data from a dataset and them summarize it by a number of different characteristics. One of them is the month in which an event is scheduled / has occurred. We have the exact date of the event in the database, something like this: person_id date_visit 1 2012-05-03 2 2012-08-13 3 2012-12-12 ... I would like to use the table() function to generate a summary table that would look

问题 My friends and I are developing an app in android studio using Kotlin. We are quite new in app development but we have decent prior programming skills. For one of our functionalities we need to get current date and time. We tried all kinds of imports and methods, but none seem to work with SDK lower than 26. With our app we target devices with minimum API 19. For example: package hr.com.wap.wap import android.support.v7.app.AppCompatActivity import android.os.Bundle import kotlinx.android
