问题 With a resample job, I have my monthly values converted to quarterly values: hs=hs.resample('QS',axis=1).mean() Works well, my columns look like this: hs.columns: DatetimeIndex(['2000-01-01', '2000-04-01', '2000-07-01', '2000-10-01', '2001-01-01', '2001-04-01', '2001-07-01', '2001-10-01', '2002-01-01', '2002-04-01', '2002-07-01', '2002-10-01', Now I want them to convert in the YYYYq[1-4] format, which I thought should be as easy as (according to this Link): hs.columns.strftime('%Yq%q') But

问题 I want to format a UTC date-time in a specific ISO 8601 format like 2020-02-28T14:10:23+00:00 but not 2020-02-28T14:10:23Z . I don't want Z at the end but +00:00. I tried all the formats in simpleDateFormat doc and no format seems to give the above-mentioned one. I know both represents same time irrespective of the format but it needs to be formatted like that for backward compatibility reasons. Here is the java code that I tried, final SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd

问题 I have a year and a week number which I want to convert into a datetime.datetiem object. My (naive?) reading of the documentation hinted that strptime('2016 00', '%Y %W') should do just that. However: In [2]: from datetime import datetime In [3]: datetime.strptime('2016 00', '%Y %W') Out[3]: datetime(2016, 1, 1, 0, 0) In [4]: datetime.strptime('2016 52', '%Y %W') Out[4]: datetime(2016, 1, 1, 0, 0) What am I doing wrong? 回答1: So it turns out that the week number isn't enough for strptime to

问题 I am trying to convert string value "2018-10-11T12:00:00Z"; to ZonedDateTime. If I use the default ZonedDateTime.parse(zonedDateTime) then ss portion i.e. 00 is removed and I get "2018-10-11T12:00Z" as output. Can you please help how to retain 00 as SS part. String zonedDateTime = "2018-10-11T12:00:00Z"; ZonedDateTime z = ZonedDateTime.parse(zonedDateTime); System.out.println(z); // return 2018-10-11T12:00Z ZonedDateTime z1 = ZonedDateTime.parse (zonedDateTime, DateTimeFormatter.ofPattern(

问题 If we have only a time in say cell A1 of Google sheets. For example, I have this: 8:09:00 AM When I use this to fetch the contents of the cell: sheet.getRange(1, 1).getValue(); this is what it returns: Sat Dec 30 1899 08:09:00 GMT-0500 (EST) Why is this happening? Any way for getvalue() to stop interpreting the data and get the raw data instead? Note: No special formatting has been set by me for the cell. So I guess the formating is the default (automatic), which is not something I want to
