Description:
------------
when calling the strtotime() function and when passing a time before the day such as "1pm yesterday" the wrong timestamp is returned, often midnite of that particular day.  


Reproduce code:
---------------
echo date('Y-m-d H:i:s',strtotime('1pm yesterday'));



Expected result:
----------------
The expected result would be 

2007-07-08 13:00:00 and this works in php 4.3.9

If I put the time after the day, such as "yesterday 1pm", it behaves as expected.  



Actual result:
--------------
2007-07-08 00:00:00

This is not a bug, but a design choice. The new parser "Executes" the different parts of the string in order. So first "yesterday" and then "1am" moves to yesterday midnight first, and then to 1am. The opposite way first moves it to "1am" of the current day, and then back to yesterday midnight.

Thanks for the insight; the process that the string is "executed" makes sense.  But why the change?  We have code written and tested with PHP 4.3.9, which is now partially broken due to the change in design choice you reference.  What might you suggest would be a work around to get the desired result, as I used to get in 4.3.9?

It was changed not deliberately, but the old parser had no design and was impossible to maintain. As for a workaround, switch around "yesterday" and "1am" ?
