What is the difference between storing dates and storing images (UI Image) in memory?

When storing a date (Date) in memory, a unified representation is most often used, such as the number of seconds from a certain reference point (Epoch), occupying a fixed, relatively small amount of memory (usually 64 bits for TimeInterval).

When storing an image (UIImage), its pixel representation is usually stored in memory. The memory size depends on the image dimensions (width * height) and pixel format (number of bytes per pixel, e.g., 4 bytes for RGBA). Additional memory may be required for decompressing the image if it was compressed (e.g., JPEG).

Main differences:

• Data type: Date - a numerical or structured representation of a point in time. Image - a two-dimensional array of pixel data.
• Memory size: Date occupies a fixed, small amount. Image size depends on its dimensions and format, and can be significantly larger.
• Representation: Date - an abstract value. Image - a set of specific color data for each pixel.
• Operations: Arithmetic operations are applied to dates (adding/subtracting intervals). Pixel processing operations (scaling, filters) are applied to images.
