Hello!
I'm trying to develop some kind of RSS news aggregator and I want to show only feeds younger than 1day. I figured i could transform RSS pubDate to timestamp (strtotime()), but there are some feeds without timestamp (like: http://izklop.com/xmldata/rsslinks.xml). Is there any other way to do it, so I could find timestamp from those feeds without pubdate?

If there isn't any other way, do You think it is ok, to just show last 5 feeds?

I hope I made my self clear, and please forgive me for my English

Hi.

I have this code which input data to the database.
Code: [Select]
<?php


include("connect.php");

echo $date = date("Y-m-d H:i:s");
echo "\n <br />";

echo $date2 = date('Y-m-d H:i:s', strtotime("+20 seconds")); 
mysql_query("UPDATE users2 SET date2 = '$date2'");


$query = mysql_query("SELECT date2 FROM users2");
$numrows = mysql_num_rows($query);

if ($numrows != 0)
{
while ($row = $mysql_fetch_array($query))
{
$date_final = $row['date2'];
}
}
echo $date_final;
?>
Variable date2 is stored as timestamp. Now i want to display this two variable on the web, but this code doesn't work. Why? Thank you.

I have a timestamp field in my mySQL table and need to check if it's 14 day or older.  What's the best way to do this?

Any help will be appreciated

hey guys I wanting some information on the best way to store a timestamp and how I would convert that timestamp to another timezone please?   im guessing I would firstly store all timestamps to the database in GMT OR BST then convert after according to users timezone preference?   Is there a good website for this please on how this is possible...thank you

im having problem comparing timestamps in my where clause for some strange reason...my query works perfect but when adding WHERE it doesn't bring up a result although it should...I've been playing about with it for almost a day now...and it doesn't make sense

unix_timestamp values

start_date_time   1406411505 
end_date_time     1407275505
now               1406461573

my query

SELECT i.item_id, 
		         i.title, 
		         i.price,
		         @start_date_time := CONVERT_TZ(i.start_date_time, '+00:00', u.time_zone),
		         @end_date_time := DATE_ADD(@start_date_time, INTERVAL 10 DAY),
		         @end_date_time AS `end_date_time`
		  FROM items i
		  LEFT JOIN sub_categories sc ON sc.sub_category_id = i.sub_category_id
		  LEFT JOIN categories c ON c.category_id = sc.category_id
		  JOIN users u ON username = 'Destramic'
		  WHERE UNIX_TIMESTAMP(@start_date_time) < UNIX_TIMESTAMP(NOW()) 
		  AND UNIX_TIMESTAMP(@end_date_time) >= UNIX_TIMESTAMP(NOW())

if anyone can diagnose my problem I'd it would be much appreciated  

Hey there,

Thanks for taking the time to read my thread.

My issue is if I'm given a time stamp in PHP how could I calculate the number of days until that time stamp?.

Thanks for your time.

I need to set two variables for use within my pages, one containing a date as a string in format 'YYYY-MM-DD HH-MM-SS' and another containing the same date as a timestamp.

The date and time stored will take on the value passed in the url if available, else will be for the current date.  The time should always be midnight at the beginning of the date.

eg.  $datestr = '2010-09-08 00:00:00'  and  $datestamp = '1283904000'

Where a date is passed in the url, it will be in the format 'YYYY-MM-DD'.

The problem I am having is getting an accurate timestamp.  I think the trouble is connected to the handling of daylight saving time as it it always an hour out.  What I have at the present is as below:

Code: [Select]
<?php
// ensure all date and time functions are relative to the correct timezone (UK)
date_default_timezone_set('Europe/London');

// string holding selected / current date in format 'YYYY-MM-DD HH:MM:SS'
$datestr = (isset($_GET['date']) ? $_GET['date']." 00:00:00" : gmdate("Y-m-d")." 00:00:00");

// int holding selected / current date as unix timestamp
$datestamp = strtotime($datestr);
?>

Can anybody give me a simple way of converting $datestr into $datestamp to ensure that this is always correct for my UK timezone, irrespective of whether we are in or out of daylight saving time?

I'm using date_default_timezone_set("America/New_York"); to set the time, but the time isn't being displayed properly in mysql.  The time is some other time zone. 

Do I have to set the time in mysql too?  How do I do this?

upon using PHP strtotime('2010-11-23 00:00:00') output a different values.

Asia/Taipei
int(1290441600)

Europe/London
int(1290470400)

Expected : Same since I declare the date that need to convert as timestamp


date_default_timezone_set('Asia/Taipei');
var_dump(strtotime('2010-11-23 00:00:00'));

date_default_timezone_set('Europe/London');
var_dump(strtotime('2010-11-23 00:00:00'));



Any explanation, Idea or alternative?

Please help. Thanks

I need some help. I have this script that pulls timestamps from the database. What I want to do is create a count of how many of those timestamps that were returned were from the morning(6am-12pm), Afternoon (12pm-6pm), Evening (6pm-12am), or Night (12am-6am). How do I do I parse the timestamps to do that and display the count. Thanks!

Code: [Select]

$startdate = "2010-07-01";
$enddate = "2010-08-05";

//query to pull time stamps in between dates

I've been having problems displaying the correct time when extracting timestamp for a graph. Wasted a lot of time trying to adjust for timezone and then finding that it didn't help. Now trying to add 2 hours to the timestamp and not sure how. Here is the line that needs to be changed I believe. $Date=substr(mysql_result($result,$i,"Date"),11,5);  Can someone help me?
