Which time-zone meaning are we using?
Pacific Time
PT follows America/Los_Angeles. On your selected date it uses UTC−08:00 (PST). Its offset can change when the regional clock rules change.
Fixed alternatives: PST (UTC−08:00) · PDT (UTC−07:00). These labels keep their stated UTC offset throughout the year.
