RPiCam "schedule settings" current time is always GMT on Bookworm

[hogwell]

Description

When I go into the Schedule Settings in the RPi Web Cam Interface front end (v6.6.26), it shows the correct local time under "Current" time on a PiZeroW2 Buster (Kernel 6.1) installation. (i.e. the current local time)
However on a different Pi4/Bookworm (Kernel 6.6) install, this is displayed incorrectly as GMT, ignoring the local time zone setting on the computer.

Steps to Reproduce

!. On a Bookworm machine with the full RasPyCam and RPiCamWebInterface installed, launch the RPi Web Cam Interface.
2. Click "Edit Schedule Settings".
3. Check the indicated "Current Time". It should show the local time, but it shows the GMT time on my test system.
4. This is odd since the same software works fine on Buster.
5. Because this time setting is wrong, the scheduler launches actions at the wrong time.

Expected Behavior

The current time is shown correctly on a Buster system, but incorrectly on a Bookworm install.

Additional Information (Optional)

Can others reproduce this?
Is this an incompatibility with php versions between the two systems?

I tracked this problem down to the use of the deprecated php strftime() function.
It is apparently broken, but not yet removed from the language in the Bookworm Debian release.

To fix the issue, I copied a replacement for strftime() that I found here:
https://github.com/sunhater/strftime/blob/main/strftime.php

For now, I just pasted this replacement function into schedule.php and renamed it "my_strftime()". All calls within schedule.php were replaced with a call to this replacement function.

This should really involve a better fix, but it's at least working for me now!

I'll give this a try too. Thanks a lot. Seems to work till now.
