Warning: strtotime(): It is not safe to rely on the system's timezone settings.

I have had Zen Cart installed and been using it for some time but now at the logon screen I get the following:

Warning: strtotime(): It is not safe to rely on the system's timezone settings. You are required to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home2/sanguina/public_html/store/zenadmin/login.php on line 13

(I am also getting a similar warning for another script I'm using, unrelated, but that's neither here nor there.)

I can't login; it sends me to a page that repeats the warning and that's all that's on the page.

I believe I have v. 150 installed. I installed new and I believe I installed via zc_install.

My site is https://www.sanguinarius.org/store/ . How do I post my admin url without compromising security?

I use HostMonster as my hosting company.

I did several different searches for the warning before I posted this topic. This is all the info I have available right now as I can't log in and I'm not evven sure if myv password's been reset or not.

Signed,

Frustrated

What PHP version are you using?

Does this help? http://www.zen-cart.com/showthread.php?208662-date-timezone-patch-for-PHP

Using:

PHP version 5.4.17
MySQL version 5.5.32-log

I will give your suggestion a try. Thank you.

Plan A didn't work; trying plan B.

Do I use the timezone I'm in, or the timezone my webhosting provider is in?

Either will "work".
Depends how you want it to display to you.
