About the time in Ontario
The zone identifier America/Los_Angeles is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Los_Angeles keeps pointing at Los Angeles time whatever the date, which is why every timestamp on this page is built from it.
Ontario sits at latitude 34.04, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 09m is one point on that curve, not a fixed value.
Ontario runs on America/Los_Angeles, which puts the city UTC −7 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
