问题 I want to write a function that returns a table with all the rows between firstDate and lastDate . The rows have datatype timestamp without time zone They also have to be of a specific node id.

问题 I want current time to round up to next 30 mins interval. Eg: If I open the app with current time as 8:33pm, I want next 30 mins round up time to be 9:00pm. If current time is May 22 11:30pm, next round up time should be May 23 00am. I tried with below code, but that gives me the nearest round up which is 8:30pm. How can I get next round up date and time? func next30Mins() -> Date { return Date(timeIntervalSinceReferenceDate: (timeIntervalSinceReferenceDate / 1800.0).rounded(.toNearestOrEven)

问题 how to get a total month between 2 dates? here is the normal way to get a date 1) startDate: 2020-2-22 10:25:00 2) endDate: 2020-3-3 12:34:00 let diffInDate:Int = Calendar.current.dateComponents([.month], from: startDate, to: endDate).month! if we check as per the above-given date it will return 0 due to not total 30 days. now I want the result with a month difference if we check the above date it should return 1 because the month changes. so is there any way to check date difference

问题 Goal: If current day of week is any day other than Monday, display the date of the Monday of the current week. If the current day of the week is Monday, simply display today's date. ** This is what I wrote and I think it works but is probably not the cleanest way to determine the date. Having said that, does anyone see any reason why the code would be wrong or not work? ** <?php date_default_timezone_set("America/New_York"); $day = date("w"); if( $day == 1 ) {$day -= 0;} if( $day == 2 ) {$day
