问题 I'm trying to convert 2 dates to timestamps. One is generated by php (today's date) and the other is input by the user $today = date("d-m-y"); // 01-12-13 $start_date = "28-11-13"; $todaytimestamp = strtotime($today); $starttimestamp = strtotime($start_date); echo "$today > $start_date <br>$todaytimestamp > $starttimestamp"; Problem is that the result are incorrect Result: 01-12-13 > 28-11-13 1008201600 > 1857686400 what's wrong ? 回答1: Always use four-digit years, as using two-digit years

问题 Here I have a dataset with date, time and one input column. So here my time column is not good. So I want to give time range into that time column. So here first I did I just convert start time into 0 and convert whole time column into minutes. Then next what I want to give time range like 0,60,120.... Mean what I expected output is: first time convert date time time 10/3/2018 6:15:00 0 10/3/2018 6:45:00 30 10/3/2018 7:45:00 90 10/3/2018 9:00:00 165.0 10/3/2018 9:25:00 190.0 10/3/2018 9:30:00

问题 I have a database where people can book rooms within two certain times, but there may be other people searching for an available room within the same times - or partly in the same time. Database looks like this: order | room | user | date (date-format) | from (time) | to (time) 1 123 foo 2013-04-04 12:00:00 17:00:00 The problem comes when another user searches if the room is available from f.ex 13:00 to 18:00, since I only manage to search if the room is available in the exact same time.

问题 Is it possible to convert Array having binary or hex values stored as each element into 64bit Double Mac Absolute Time? When I inspect array using p var_bytes console shows following output. \000\000\000\000\000\000\000\000\000\000\000\234\225x\266A\000\000\000\345\005\230\264 Is it possible to convert above array elements in 64bit Double Mac Absolute Time as a string? My code is following just a simple do..end puts "\nClose off the page header#{y.unpack("n")}\n" z.scan(/(.{8})(.{8})(.{4})(.
