I have dates like this Date1="Wed Oct 21 13:05:14 2012" Date2="Wed Nov 21 12:55:30 2010" Date3="Wed Nov 21 14:22:30 2012" How do I find out the latest date? 回答1: The unix date command can convert date formats,

问题 I am trying to format a timestamp but the wrong value is returned. let timestampDouble: Double = 1455970380471 let timestamp = NSDate(timeIntervalSince1970: timestampDouble) let formattedTimestamp = NSDateFormatter.localizedStringFromDate(timestamp, dateStyle: .MediumStyle, timeStyle: .ShortStyle) formattedTimestamp returns Jun 22, 48115, 8:49 AM instead of the correct timestamp of Feb 20, 2016, 11:13 PM (from epochconverter.com). 回答1: You've got the wrong value. I reversed the process,

问题 I am doing research in a MySQL database, and I suppose some timestamps are in Unix format. Those timestamps are in a bigint(20) field. I'm going crazy about them. How can I convert these to a regular timestamp? Example: 634583466272408810 634587264000000000 回答1: try select from_unixtime(634583466272408810/1000000000) See FROM_UNIXTIME 来源： https://stackoverflow.com/questions/12090772/unix-timestamp-bigint20

问题 I'm trying to convert this unix timestamp 1415115303410 in DateTime, in this way: private static DateTime UnixTimeStampToDateTime(long unixTimeStamp) { System.DateTime dtDateTime = new DateTime(1970, 1, 1, 0, 0, 0, 0, System.DateTimeKind.Utc); dtDateTime = dtDateTime.AddMilliseconds(unixTimeStamp); return dtDateTime; } But I get a wrong date: Date: {04/11/0045 00:00:00} NOTE: dtDateTime.AddSeconds(unixTimeStamp) throws an exception.. my number is in Milliseconds. with this online conversion

问题 I know there a lot of questions and answers of this already, but unfortunately I think my situation may be unique? For some reason, the time-change seems to be making the day calculate as one day less than it should be calculating. Here is my PHP that I was using and it was working great, until it started to overlap a start and end date that was BEFORE daylight savings, and AFTER daylight savings, respectively (FYI, this is a recent issue, since daylight savings time starts this weekend!): //

问题 My DB design includes multiple MYISAM tables with measurements collected online, Each row record contains auto-incremented id, some data and an integer representing unixtime. I am designing an aging mechanism, and i am interested to use MySQL partitioning to partition each such table based on unixtime dynamically. Say that i am interested that each partition will represent single month of data, last partition should represent 2 months, if records arrive for the next not represented month, the

问题 Assuming you have a Unix timestamp, what would be an easy and/or elegant way to check if that timestamp was some time yesterday? I am mostly looking for solutions in Javascript, PHP or C#, but pseudo code and language agnostic solutions (if any) are welcome as well. 回答1: PHP: $isYesterday = date('Ymd', $timestamp) == date('Ymd', strtotime('yesterday')); 回答2: In C# you could use this: bool isYesterday = DateTime.Today - time.Date == TimeSpan.FromDays(1); 回答3: You can use this in C#: bool

问题 I'm trying to store in timestamp with timezone field my value. It is in milliseconds from 1970. select TO_CHAR(TO_TIMESTAMP(1401432881230), 'DD/MM/YYYY HH24:MI:SS.MS') Expected 30/5/2014 11:29:42 10:54:41.230 , but get 22/08/46379 23:27:02.000 回答1: Unix timestamps measures time with seconds, and not milliseconds ( almost everywhere, in PostgreSQL too). Therefore you need to call SELECT TO_TIMESTAMP(1401432881230 / 1000); If you want to preserve milliseconds, call with double precision :

问题 I'm looking for the best practice/solution to book a service internationally, using same time in any browser. I don't quite get the logic (and dug around here too). Use case user in Brussels booking lets say a haircut service based in Singapore - he is flying there in a week. He picks 14:00 in the browser datetime control. The browser is, however, set to +1 UTC. SG haircut stylist should see the time in his agenda as 14:00 SG time. the barber shop owner is traveling at Dubai, and he wants to
