Mutable date objects create hidden bugs in billing and scheduling code. Here is how CarbonImmutable returns new instances instead of mutating shared references, plus a practical migration path.
Goal: achieve consistent date representation in Backbone.js models so that client‑side views display the correct local time while server APIs receive predictable values. Constraints: Backbone.js has no date‑specific utilities; it treats a Date attribute as a plain JavaScript Date and its toJSON method converts it to an ISO‑8601 UTC string, which can drop the
Date Conversion Behavior Matplotlib utilizes internal float representations for dates on axes. A significant change occurred in version 3.1, where the reference epoch shifted from 0001-01-01 to 1970-01-01. This shift affects how matplotlib.dates.date2num and num2date interpret raw float values. Compatibility Constraints When migrating legacy data or using pi
