date

问题 This question already has answers here : PostgreSQL: Index the day part of a timestamp (2 answers) Closed 4 years ago . I am creating a summary table that sums up all events in a given day. INSERT INTO graph_6( day, event_type, (SELECT COUNT(*) FROM event e WHERE event_type = e.event_type AND creation_time::DATE = sq.day) FROM event_type CROSS JOIN (SELECT generate_series( (SELECT '2014-01-01'::DATE), (SELECT '2014-01-02'::DATE), '1 day') as day) sq; The creation_time column is indexed:

问题 I'm trying to get the current date without the time and store it in a variable, within JavaScript. It needs to be without time as I'm converting it to an epoch date, with which I will use to measure the past 24 hours (if date is within 24 hours then it will be displayed). The problem is that with the added time, it doesn't match as within the last 24 hours. e.g. it returns the date as the following when converted to epoch: 1408704590485 I want it to be like 1408662000000 I'm not to sure how

问题 I'm trying to leverage Google Calendar (and Google Calendar API) for simple scheduling. I'm using PHP, MySQL and google-api-php-client. I'm looking for a algorithm or pseudocode to find open time slots. My calendar has events for busy times such as when business is closed and for current appointments. I am able to retrieve event start and end times via two function (Events: list and Freebusy: query). Here is a example list of events for today with start time of 2016-02-19T01:00:00-07:00 and

问题 I'm writing a vba subroutine in excel to store all date values between 2 dates in a single dimension array and then check for each value in a range on another sheet. My problem is when the code is grabbing the date values (as an integer(or double - whichever one it is actually using)) it is storing a value 1462 greater than the date value on the sheet. I am using the 1904 date system so I can use negative time values and i'm in Australia so dates are formatted dd/mm/yyyy. As an example; On

问题 I try to compare two days ignoring time. So I use calendar.compare(date1, to: date2, toGranularity: .day) BUT when transfering the string date to Date type, it is transformed to UTC. So it will be "moved" from 1.1.2016 0:05 to 31.12.2015 11:05 pm. When comparing daywise, this includes only the remaining hour. Before conversion it was 24 hours. Any idea to handle this issue without much effort? Additionally: The code: var dateFormatter = DateFormatter() dateFormatter.dateFormat = "dd-MM-yyyy
