Null Pointer Exception Error from new lines of code

I've added just a few lines of code for time zone handling and the page is now throwing an error on submit.

I added these lines in the submit method:
User-added image

adjustment is a public variable declared in the top of the code. 

Here is my error from the log (screenshot):

Hello Jean,

Place a system debug before line 248 to make sure your fields and variables has value and are not null: 
system.debug(o.Director__r.TimeZoneSidKey);
system.debug(apptdate);

Hope to have helped!

If they are null you should consider revising your code, the data, or skipping this part of the code when there is no value.

Thank you, I debugged and saw that the Director TimeZoneSidKey is null, but the Director is not null and I can see in the user data that the timezone is populated. How is this possible?

Please check if condition before 248 line 
if( o.Director__C.TimeZoneSidKey !=null)
Let us know if this will help you

Hello Jean,

Director is a lookup for the User sObject right? Can you please share your query? I also suggest you to run the same query in the Developer Console to see if it's working as expected.

Hope to have helped!

I was able to resolve this by accessing the user timezonesidkey via query before the code I added. Thank you for your help!
