DateTime in .NET - Things I learned (#1?)

Here's what I looked like while learning about DateTime in .NET:

What do I think they are?

Like with strings, I can't be too sure.

I know that at its core, DateTime mostly works on some form of integer as "ticks" to determine the current time. DateTime comparison and addition then becomes quite easy.

Though I couldn't say what the default Time Zone information is and how that gets converted.

5 things that I learned while looking at DateTime

• DateTime data is stored as a ulong but is actually treated as bytes
  • The first 62 Bits is the value of 100-nanosecond ticks
  • Bits 63-64 are to denote DateTimeKind
• C# DateTimes have a range of 01/01/0001 12:00:00 AM until 31/12/9999 11:59:59 PM
• The DateTimeKind Enum can be helpful for ensuring you're dealing with DateTimes Consistently
• Wtf is the | Operator?
  • It's called a Bitwise OR Operator
  • It's REALLY interesting, and is used to combine add Bits together.
  • I hate it
• But what are Structs actually?
  • There's some interesting differences between Structs and Classes outlined in this blog https://www.c-sharpcorner.com/blogs/difference-between-struct-and-class-in-c-sharp

What were the differences?

I thought that the DateTime data was just a simple ulong, but it's clear that it's being used in a more complex way than I initially thought. I feel like I've barely scratched the surface on this one, so I'm excited to jump back into it later.
