yeah it should be closed, sorry for the typo.
this way:

When I add a closing ] to it as such:

One person asked about missed punches. What happens if someone forgets to clock out? Is an entry made for the person for the appropriate day/minutes/sequence ??? I can see a way to do what you are asking, but I need these questions answered first. Okay, here's what I have figured out about how the original programmer did it. Employees are given the option of using a clock in/clock out link on the web page or entering the hours manually. Most of the employees just sign in/out at the end of the day. The sequence number is used to keep it in order so that it can do the math based on the right day. sequence 0 is the first sign in, sequence 1 is the first sign out, sequence 2 is the second sign in, sequence 3 is the second sign out etc. etc.. Basically if an employee works from 8:00 AM until 4:30 PM with a half hour lunch the database would look something like this: Sequence 0 480 (8 AM) IN Sequence 1 720 (12 noon) OUT Sequence 2 750 (12:30) IN Sequence 3 990 (4:30) OUT Or if they work until 7 PM with a break for lunch and supper it would look like: Sequence 0 480 (8 AM) IN Sequence 1 720 (12 noon) OUT Sequence 2 750 (12:30) IN Sequence 3 990 (4:30) OUT Sequence 4 1020 (5PM) IN Sequence 5 1140 (7PM) OUT The idea being if you sort by employee, day, and then sequence you can do the math by subtracting sequence 0 from sequence 1, sequence 2 from sequence 3 etc. etc. When I started looking at this originally, I was just looking at adding a feature to it, but now I'm thinking that since I've learned a fair amount about working with databases, I may try and write my own as a side project to learn even more :) I will try the suggestions that were given and any new ones that come in and see what works best, and when I do that I'll post the results back here for posterity. Thanks everyone for your help! It's because of people like you that I have been able to come as far as I have in this world. -- Jason Pruim [EMAIL PROTECTED] Production Technology Manager MQC Specialist (2005 certified) 3251 132nd Ave Holland MI 49424 616.399.2355 www.raoset.com “Give me your tired, your poor, Your huddled masses yearning to breathe free, The wretched refuse of your teeming shore.

Re: [PHP] Date/time format?
Thanks everyone for your suggestions, it turns out it was a unix time
stamp and I can get it to parse out a normal date now.
Now... on to the harder part
What I am trying to do is learn... This is kind of just a pet project
for me to figure out how I can do it. here is how the database is
laid out:
+---++-+-
+--+
| user | day|
job_name | minutes | sequence |
+---++-+-
+--+
| root | 1172466000 | Production technology Manager | 480
|0 |
| root | 1172466000 | Production technology Manager | 720
|1 |
| root | 1172466000 | Production technology Manager | 750
|2 |
| root | 1172466000 | Production technology Manager | 990
|3 |
the minutes column is the number of minutes that have passed since
midnight. the sequence number refers to the sequence that the times
were entered, meaning that 480 minutes after midnight came before 720
minutes, which was before 750 minutes which was before 990 minutes.
What I need to do, is be able to calculate the time between 0 1, 2
3, 4 5 (there is a total of 6 sequences that could be in here)
here is now the math would like on that particular entry: (480-720) +
(750-990)=480/60=8 hours.
This is a timecard program that I'm trying to write a report for to
show the time for the entire month instead of it's default for the
week. You can see what I have tried live at: raoset.com/tests/
oatstest/oats.shtml
the code that I need help with is the math. I have looked but I just
can't find a clear way to get the info from mysql, into an array in
php to do the math? Maybe I've been looking at it to long and so I'm
missing easy stuff?
I have tried this code:
$querytime = mysql_query(select sum(minutes) as t1, sum(sequence) as
t2 from oats_time);
while($row = mysql_fetch_array($querytime)){
$fulltotal=$row['t1']+$row['t2'];
echo($fulltotal);
}
but that didn't work the way I wanted it to.
Anyway... Post is long enough to start, so let me know if there is
other info you need.
Thanks in advance!
