问题 How do I use Unix timestamps with the Doctrine Timestampable behavior? I found the following code snippet here, but I'd rather not manually add this everywhere: $this->actAs('Timestampable', array( 'created' => array('name' => 'created_at', 'type' => 'integer', 'format' => 'U', 'disabled' => false, 'options' => array()), 'updated' => array('name' => 'updated_at', 'type' => 'integer', 'format' => 'U', 'disabled' => false, 'options' => array()))); 回答1: This is a question that might get an

问题 My problem is pretty straigtforward explained : if I do this : public class Main { public static void main(String[] args) throws Exception { Date d = new Date(0L ); System.out.println(d); } } I get the following output : Thu Jan 01 01:00:00 CET 1970 According to the doc, I was expecting : Thu Jan 01 00:00:00 CET 1970 I would like was going wrong... EDIT : Indeed, I read the doc too fast. I should have Thu Jan 01 00:00:00 GMT 1970 So, how can I force the use of GMT, and ignore all local time ?

问题 I use jqGrid and my grid definition is like that: ... colNames:['Type','Date','Message','User Name','Host'], colModel:[{name:'type',index:'type', width:100}, {name:'date',index:'date', sorttype:'date', formatter:'date', formatoptions: {newformat:'d-M-Y'}, width:100}, {name:'log',index:'log', width:200}, {name:'username',index:'username', width:50}, {name:'host',index:'host', width:50}], ... When I debug my coming data one of the date value (it is Number) is as follows: 1322550786997 Grid

问题 I have a bash question (when using awk). I'm extracting every single instance of the first and fifth column in a textfile and piping it to a new file with the following code, cut -f4 test170201.rawtxt | awk '/stream_0/ { print $1, $5 }' > testLogFile.txt This is part of the file (test170201.rawtxt) I'm extracting the data from, columns Timestamp and Loss , Timestamp Stream Status Seq Loss Bytes Delay 17/02/01.10:58:25.212577 stream_0 OK 80281 0 1000 38473 17/02/01.10:58:25.213401 stream_0 OK

问题 I am facing some problems in a cross platform program: when I open a python shell in Linux and in Windows, I don't get the same time from the Epoch. In Linux, I tried to do dpkg-reconfigure tzdata . Currently, in linux I get that avec the dpkg-reconfigure tzdata: Current default time zone: 'Europe/London' Local time is now: Mon May 30 10:29:52 BST 2011. Universal Time is now: Mon May 30 09:29:52 UTC 2011. Then, in the python console, I create this script: import time print time.tzname, time

问题 I am trying to convert string in following format: 20130817T140000Z (17th Aug 2013 at 14:00) to epoch time (seconds since 1970) in an MS Excel 2013. Tried cell formatting, but it doesn't work with T and Z or the format in general. 回答1: This will convert your date into somethign Excel will understand, If you have your date in Cell A1, Then convert that into Epoch Time =(DATE(LEFT(A1,4),MID(A1,5,2),MID(A1,7,2)) + TIME(MID(A1,10,2),MID(A1,12,2),MID(A1,14,2))-25569)*86400) 回答2: Try this: A1

问题 Is the epoch start time in Python independent of the platform (i.e. always 1/1/1970)? Or is it platform dependent? I want to serialize datetimes (with second accuracy) on various machines running Python, and be able to read them back on different platforms, possibly also using different programming languages (than Python). Is serializing epoch time a good idea? 回答1: The documentation says: To find out what the epoch is, look at gmtime(0) . I would interpret this to mean that no particular

问题 So I read this very interesting blog on working with datetime in Azure DocumentDb. The problem being that, right now, Azure DocumentDb does not support range search on datetime fields. The reason for that is that DocumentDb is based on json and that has no datetime type, therefore one usually puts it in a string of xml datetime format. (obviously Mongo does not have that issue, it's bson format adds the datetime type (among others)) Anyway, the article describes storing the datetime in json
