timestamp

[Banana Man]

Hi,

Im working with timestamps for the first time so just want to check something.

If i have a time stamp ( $timestamp ) and want to add a certain amount of time is this how its done?

Add 5 hours: $timestamp + (5 * 60 * 60)

Add 2 mins: $timestamp + (0 * 2 * 60)

Thanks

Check "Example 440. A strtotime() example".

Might be a little easier for you.

Add 2 mins: $timestamp + (0 * 2 * 60)

Multiplying something by zero always yields a zero result.

Ok, then ive got the concept all wrong. How would you go about adding 2 minutes to a timestamp?

[bokehman]

2*60 = 120
but
0*2*60 = 0

Pretty primary school really!

Just be aware that manually adding seconds to your time stamp won't take daylight savings into account when the before/after date crosses a transition from when daylight savings is in effect.

Thats a good point actually. It wont affect this function but something to take into account in the future.

Have a look at the date and time functions in the PHP manual, when I started using dates I found that they were very cumbersome, but actually, there are loads of functions built into PHP which make date and time manipulation easy.
