Hi Everyone
I need help knowing how to calculate midnight “X” days ago in whatever time
zone the user has selected.
- The context of this is creating a report
- An Example: I am want to base the report on records created between
2013-11-01 00:00:00 and 2013-11-07 23:59:59 in the users time zone
The report I am generating is based on date – time in the column
“occurance_date”. This column is type “datetime”. All dates – times in this
column are in GMT time zone.
I want to calculate the starting and ending dates – times using PHP (Since the
user selects their time zone based on the available PHP time zone list) and
then bind them to the database query:
===
SELECT * FROM `journal_entry` WHERE `occurance_date` BETWEEN :starting_date AND
:ending_date ORDER BY `occurance_date` ASC
===
I normally use the following code to convert between time zones. But I don’t
know how to calculate what time it is in GMT time zone when it is midnight in
the users time zone X days ago, or midnight on November 1st 2013 in the users
time zone.
===
$date = new \DateTime( date('Y-m-d H:i:s') , new \DateTimeZone(
'Canada/Eastern' ));
$date->setTimezone(new \DateTimeZone( $_SESSION['logged_in_timezone'] ));
$starting_date = $date->format('Y-m-d H:i:s');
===
Some reports I am going to be creating will be:
- last 7 days
- last 14 days
I also need to be able to do reports which are based on:
- The month of November 2013
- The last 3 months
I hope this paints a clear picture of what I am working on. If you need
clarification please ask me. Thank you for helping me. Ron
