[PHP] Issue with STRFTIME and Daylight Savings

[Malcolm Green]

Hi Support:

I've moved into a new role and inherited a system which uses the 'STRFTIME'
function to create a filename in the form 'strftime("%Y%m%d")'; the
filename is supposed to be "today's date". (Note I've left out the file
extension for clarity.)

I've noticed that system creates the wrong filename when the process runs
between midnight and 12:59am, during Daylight Savings time. That is, it
creates a filename equal to "yesterday's date". When run at 1:00am or
later, everything OK.

I've checked the Date/Time and 'Locale' settings in Windows, and everything
is ok. My initial thought was that STRFTIME was looking a the system clock
rather than Windows (?).

Can you help?

(PS ... please be gentle, I'm a novice at PHP!)


Thanks & Regards,
Malcolm.

Hi Rob:

Thanks for the feedback.

Just to throw one in from "left field", the script is written in AWK, not
PHP (told you I was a novice!)

Have confirmed that 'systime' refers to hardware clock, so I have a quick
and dirty work-around by adding '3600' (seconds) to STRFTIME, but will look
into a cleaner solution.


Thanks & Regards,
Malcolm.

Check your timezone settings in php.ini
