DST和PHP日期和时间戳

Question

I have searched the list for an prior answer, but can't find one. We are using PHP 4.4.8 and need a PHP 4 answer. We have an array of timestamps [$d] representing:

1478404800 2016-11-06 00:00:00

1478494800 2016-11-07 00:00:00

2016-11-06 is the transition day for DST to Std time.

We want to store a timestamp that represents 1:00pm on each day, so we did

$e2 = $d+46800

46800 is 13 hours worth of seconds.

date("D d M Y g a I",$e2)

returns:

Sun 06 Nov 2016 12 pm 0

Mon 07 Nov 2016 1 pm 0

The trailing 0 is the DST indicator. Nov 6 seems to be indicating the DST to STD "fallback" 1 hour. We don't want DST reflected.

So the questions are:

1. How do we get a Nov 6th answer that doesn't reflect DST to STD.

2. If this is DST, why for one day? Nov 7th didn't get any "fallback"

Users are not in different time zones, so we needn't worry about time zones.

Answer 1

It's unclear what you're asking for exactly, but if your only concern is the date() return value - tell PHP to create the correct UNIX timestamp:

mktime(13, 0, 0, 11, 6, 2016);

Though, I'd be more concerned that you're still running PHP 4 on this date.
