Suggestion on faster solutions for extremely large database.
$ledip['started'] = '2009-04-01 13:40:34'; Example time in DB
$ledip['touchedlast'] = '2009-04-01 13:41:28'; Example time in DB
date('i:s', strtotime($ledip['touchedlast']) -
strtotime($ledip['started'])); // Not a desired solution because of its
inability to go past the minute correctly I AM AWARE.
or
concat( truncate( hour( timediff($ledip['touchedlast'],$ledip['started']) )
/24, 0 ) , days , hour( timediff($ledip['touchedlast'],$ledip['started'])
) %24, hours , minute( timediff($ledip['touchedlast'],$ledip['started'] )
) , minutes , second( timediff($ledip['touchedlast'],$ledip['started'] )
) , seconds ) as timeleft
The results of concat truncate, allows me the flexibility or exacting time
differences out past the minute. I am worried that the vastness of the
database may cause me a server load or query timeframes that are undesirable
as it grows even bigger.
Suggestions?

Do not reply to this email with your 9 million page thought of how to, or
some custom function that you think is all that, I do not care.
I am asking for load desired results NOT your take on my code…

You are doing a lot of calculation on this combining both PHP and SQL code.
How many rows are you affecting with this query at one time?
I hate to say it, but this to me is just begging for a unix timestamps, then
you can simply deal with the seconds remaining on this counter.
