Reading UTC timestamps on the West Coast
Developers and operations teams in California read UTC all day: build logs, incident timelines, cloud consoles and commit histories are often stamped in it. A deploy logged at 03:15 UTC on a Wednesday in July happened at 8:15 PM PDT on Tuesday.
For quick reading, remember two anchors: 16:00 UTC is 8:00 AM PST (9:00 AM PDT), and 00:00 UTC is 4:00 PM PST (5:00 PM PDT) the day before.
