oracle 19c rac cluster nodes show in different time zones

working on an oracle 19c 2-node rac cluster. we were running awr reports when we noted in sys.dba_hist_snapshot that the cluster nodes were in different time zones. We have validated that our s_crsconfig files on each server both show America/Los_Angeles as the time zone. timedatectl also shows that the nodes are both in the same time zone (America/Los_Angeles / PST8PDT). (1) How can I tell which time zone each node thinks it is in? (2) How can I resolve this so that both nodes agree on the time zone? Thank you.
