About the time in San Diego
Clocks in San Diego stay put all year. There is no summer-time switch to remember, so UTC −6 is what you will get in January and in July alike — useful if you book recurring calls with people in Mexico.
If you are coordinating from another country, the shortcut is the working window: a normal San Diego day of 09:00–17:00 falls between 15:00–23:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
San Diego sits at latitude 25.57, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 12h 50m is one point on that curve, not a fixed value.
