问题 I have a Mysql database table and it has a column "Created time" which has values like 1538899092000 , 1543476095000 and so on. What is this ? and how to convert this into our regular format ? Thanks in advance. 回答1: It looks like a Unix timestamp multiplied by 1,000 (i.e. in milliseconds rather than seconds). These kinds of timestamps are used in JavaScript. Use FROM_UNIXTIME(created_time/1000) to convert it to a DATETIME . mysql> select from_unixtime(1543476095000/1000); +------------------

问题 How do I represent a long value in KB like the snapshot picture? 回答1: This is probably what you're looking for: long memory = 210957130; Console.WriteLine("{0:N0} K", memory / 1024); Console.WriteLine(string.Format(new CultureInfo("en-US"), "{0:N0} K", memory / 1024)); If you'd like to use the thousand separator from your current regional settings, use the first option. If you specifically want to use a comma, use the second option. 回答2: From my blog: static string ReadableFileSize(double

问题 I am trying to read a text file into an Oracle database using the Data Import Wizard in SQL Developer. I am stuck on step 5 because I cannot get the Verify parameters before import to succeed on my timestamp fields. Going back to step 4, I have tried changing the Data type of my timestamp fields to Timestamp , Timestamp with time zone , and Timestamp with local time zone . In desperation, I even tried Date .

问题 I'm trying to format a date to say how much time is left (in a readable format) from how many seconds are left: <?php $seconds = 23414; $date = new DateTime(); $date->setTime(0, 0, $seconds); echo $date->format('z G:i:s'); ?> This example might output something like: 344 11:46:45 which is not what I'd like. It should say something like 6 days, 4:12:36 . I just don't see anything here: http://www.php.net/manual/en/function.date.php that would help me format it correctly. Ideas? 回答1: I don't
