Clock and Brightness
Blipscope keeps accurate time and manages its own screen brightness, including dimming itself at night.
On every boot Blipscope synchronises its clock from internet time servers (NTP, via pool.ntp.org), so the time is always accurate without a battery-backed clock or any manual setting.
The clock runs internally in UTC. To show your local time, set the Clock UTC offset (hrs) on the Configuration Reference page. Half-hour zones are supported (e.g. 5.5 for India, -3.5 for Newfoundland). Blipscope pre-fills a sensible default offset estimated from the longitude you configure, so it's usually close out of the box — adjust it for your exact zone and for daylight-saving time.
With Auto-dim at night enabled, Blipscope automatically dims the display after dark and brightens it again at dawn. Rather than using a fixed clock time, it calculates the real position of the sun for your configured location and the current UTC time using the NOAA solar equations — so it tracks your actual local sunrise and sunset throughout the year. No light sensor required.
The Brightness slider sets the display's day-time backlight level (from dim to full). The backlight is driven by PWM, so it's smoothly dimmable. When auto-dim is active, this is the level Blipscope returns to during daylight.
