Work out the percentage of the day that has elapsed

Question

Slightly strange question, but hopefully someone can help.

In essence, if the time was 12pm the the elapsed percentage would be 50%, 6am would be 25% and 16pm would

Answer 1

gettimeofday(true) returns the number of seconds elapsed since midnight as a float (I think), so you want: gettimeofday(true)/(60*60*24). Multiply by 100 to get a percentage.

EDIT: Actually, gettimeofday returns the number of seconds elapsed since the start of the epoch, so you need to subtract midnight:

$midnight = strtotime('00:00');
$epochseconds = gettimeofday(true);
$timeofdayseconds = $epochseconds - $midnight;
$timepercent = $timeofdayseconds/(60*60*24)*100;
