UTC
A globally used time standard that allows teams across time zones to align on time. It is the conventional time notation used in cloud service status announcements.
Core Facts
Timeline (last 90 days)
The UTC window 16:30–00:30 crosses UTC midnight, so the judgment logic must be written as "utcMinutes >= 990 || utcMinutes <= 30"; a simple range comparison will go wrong.
Poland is in the Central European Time zone (CET), with standard time as UTC+1 and daylight saving time (CEST) as UTC+2.
When the clocks are set back, the scheduler insists on running in UTC, so the slot originally corresponding to 09:00 Polish time becomes 08:00, an hour earlier, and the other slot goes from 16:00 to 15:00.
The comment on the crontab entry states that the two films are released at 09:00 Polish time on Wednesday and Sunday respectively; this conversion holds during daylight saving time and shifts when the clocks are set back.
The developer added a crontab entry as `crontab(hour=7, minute=0, day_of_week="3")`, passing the arguments `{"fmt": "long", "series": "bajka"}`, triggered every Wednesday at 07:00 UTC.
The International Bureau of Weights and Measures (BIPM) voted to pass a resolution to stop adding leap seconds to UTC.
The current UTC is designed to differ from UT1 by no more than 0.9 seconds, that is, |UT1−UTC|<0.9s.
Coordinated Universal Time (UTC) relies on the coordination of atomic clocks and the Earth's rotation, maintaining closeness to solar time through the leap second mechanism.
ITU-R Recommendation TF.460 defines the composition of UTC, its fixed offset from TAI (currently 37 seconds), and the mechanism for announcing leap seconds.
Upgrading the time transfer system requires satellite navigation systems (such as GPS and Galileo) and fiber-optic time transfer networks to support the new UTC definition.

A robust scheduling system should store all timestamps in UTC and perform localized conversion at the presentation layer based on the user's current context.

50%UnverifiedThe article proposes an architectural invariant: all internal state, transaction logs, interest accrual calculations, and the database persistence layer must operate exclusively in UTC, with local time zones handled only as a view-layer concern.
