date

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 This question already has answers here : Check if string has date, any format (2 answers) Closed 3 years ago . I am trying to write a regular expression to catch different format of dates. The sentences are in a series and each sample of the series contains only one date, but may have other numbers.

问题 I have following code to get different parts of current system Date (10-11-2011 for this case). Calendar now = Calendar.getInstance(); String dt = ""+now.get(now.DATE)+"-"+now.get(now.MONTH)+"-"+now.get(now.YEAR); Here, DATE and YEAR fields are giving values as expected but MONTH field is giving unexpected results, firstly I didn't knew that MONTH field starts with zero, so having current month as 11 will give me 10 . Now, if I use now.get(now.MONTH+1) than it returns 46 . And using simply

问题 Hi all: I am struggling to color points by date in ggplot2. There are two outcomes that would work for me here. 1) colour the points by the variable recent_elections and just add straight lines denoting the date of the most recent election for each point. The current code does that. 2) preferably, but harder, just add the lines, coloured differently for each election, showing a legend that printed the date of the most recent federal election. My current data and attempt is below. library

问题 How do I categorize each row in a large R dataframe (>2 million rows) based on date range definitions in a separate, much smaller R dataframe (12 rows)? My large dataframe, captures, looks similar to this when called via head(captures) : id date sex 1 160520 2016-11-22 1 2 1029735 2016-11-12 1 3 1885200 2016-11-05 1 4 2058366 2015-09-26 2 5 2058367 2015-09-26 1 6 2058368 2015-09-26 1 My small dataframe, seasons, looks similar to this in its entirety: Season Opening.Date Closing.Date 2016 2016

问题 I have been scouring stack and google to find a way to extract a date from timestamp w/o the trailing zero's still being a date and NOT a VARCHAR variable- for example: SELECT TRUNC(to_date('2012-07-18 13:27:18', 'YYYY-MM-DD HH24:MI:SS')) FROM DUAL gives: 18-JUL-12 00:00:00 I want it in '18/07/2012' date format in the end. TIA in advance if this is possible. 回答1: I have been scouring stack and google to find a way to extract a date from timestamp w/o the trailing zero's still being a date and

问题 Is there any ways to calculate working days between two dates in snowflake without creating calendar table, only using "datediff" function 回答1: After doing research work on snowflake datediff function, I have found the following conclusions. DATEDIFF(DAY/WEEK, START_DATE, END_DATE) will calculate difference, but the last date will be considered as END_DATE -1. DATEDIFF(WEEK, START_DATE, END_DATE) will count number of Sundays between two dates. By summarizing these two points, I have

问题 I have a multiple dataframe dictionary where the index is set to 'Date' but am having a trouble to capture the specific day of a search. Dictionary created as per link: Call a report from a dictionary of dataframes Then I tried to add the following column to create specific days for each row: df_dict[k]['Day'] = pd.DatetimeIndex(df['Date']).day It´s not working. The idea is to separate the day of the month only (from 1 to 31) for each row. When I call the report, it will give me the day of
