date

问题 I want to delete all records with dates before 20 minutes ago. Postgres (or Sequelize) is not satisfied with the bare javascript Date object I provide as the comparison value. I'm using sequelize 4.37 on top of a postgres 9.6 database. The column in question was declared with type: Sequelize.DATE , which research suggests is equivalent to TIMESTAMP WITH TIME ZONE : a full date and time with microsecond precision and a timezone signifier. (That is also what I see when I use the psql CLI tool

问题 It looks like Safari's implementation of Int.DateTimeFormat assumes that the second Sunday in March will ALWAYS be the DST time cutoff which is not correct as prior to 2007 it was the first Sunday in April. It also appears that this affects the other end as well when DST ends. PS: This code is being run in Indiana, USA which is in the eastern time zone (GMT-4) More specifically... 2007 and newer: correctly for all dates. 2006: incorrectly for dates between the second Sunday in March and first

问题 I am dealing with hourly data in which the date is stored in 4 different arrays, one for day, month, year, and hour. I am running a for-loop to rather store these dates as strings with this format: '01/01/1946 0' My code looks something like this: import numpy as np from datetime import datetime as dt import matplotlib.dates as mdates for nn in range(nnn): y1 = int(yr[nn]) m1 = int(mon[nn]) d1 = int(day[nn]) h1 = int(hr[nn]) #In the the last string we are specifying the format datenow = dt

问题 So I'm trying to follow the docs here on MDN regarding the date options for formatting https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/DateTimeFormat For the cs-cz locale, I want the month to be in "short" hand form when writing a date such as 19. 12. 2012 instead of 19. pro 201 This code works for locales such as en-us or it-it (italy) and others. var date = new Date(Date.UTC(2012, 11, 20, 3, 0, 0, 200)); var options = { month: 'short', day: 'numeric',

This is my code, i take it mainly from here: http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/datepicker/client/DatePicker.html // Create a date picker "FROM: " final DatePicker datePicker1 = new DatePicker(); datePicker1.addValueChangeHandler(new ValueChangeHandler<Date>() { public void onValueChange(ValueChangeEvent<Date> event) { Date date1

问题 This question already has an answer here : Force 4-digit-year in localized strings generated from `DateTimeFormatter.ofLocalized…` in java.time (1 answer) Closed 2 years ago . I've been looking at the Date and Time library in Java 8 and was wondering if there is a way to format the date to the local format regardless of where the program is being run (as in, using the local format of the region the computer is set to). The Date and Time library uses the LocalDate class for getting a date.
