@Adam and @Lawi, as a way of procrastinating working, I also tried using PHP: <?php //this assumes that the start time is the same every day, i.e. every day at 0600Hrs, the output below is e.g. 2013-05-02 06:00 $start_day_time = date('Y-m-d 06:00'); $start_day_time_timestamp = strtotime($start_day_time); echo "Start time: $start_day_time. Timestamp: $start_day_time_timestamp <br/>"; //this assumes that the end date is the same every day, i.e. every day at 1800Hrs, the output below is e.g. 2013-05-02 18:00 $end_day_time = date('Y-m-d 18:00'); $end_day_time_timestamp = strtotime($end_day_time); $end_day_time_timestamp = mktime(0, 0, 0, date("m") , date("d")+2, date("Y")); echo "End time: $end_day_time. Timestamp: $end_day_time_timestamp <br/>"; /* What if the end time is 2 days from today, at 1800Hrs? $end_day_time_timestamp = mktime(0, 0, 0, date("m") , date("d")+2, date("Y")); */ //so what is the timestamp now? $now_timestamp = strtotime("now"); echo "Now: $now_timestamp <br/><br/><br/>"; //based on the start and end timestamps, are we allowed to run now? if ($now_timestamp >= $start_day_time_timestamp AND $now_timestamp <= $end_day_time_timestamp) { echo 'Yay! It can run!'; } else { echo 'Nope! No run.'; } ?> On Thu, May 2, 2013 at 10:46 AM, Adam Nelson <adam@varud.com> wrote:
@francis I think he's using the word 'timestamp' loosely as the time of day. But yes, as everyone agrees so far, just use the timestamp which has all the date information and then comparison is trivial.
Since we all seem to be having fun wasting time on a Thursday, I did it in Python for demonstration purposes. I set 'a' to now and then 'b' to now a few seconds later and then arbitrarily set 'c' to a time within the period. This is date-sensitive.

A timestamp will have all these details and you can extract the relevant details from it. I.e. datetime has both date and time. You can use the time or date where relevant. This is the essence of a timestamp.

@Lawi, does the start times change per day or are they sorta fixed at a preset time?
Say, every day at 0600Hrs is the start, and every day at 1800Hrs is the end
