Missing explanation

https://learn.microsoft.com/de-de/dotnet/api/system.random.-ctor?view=net-8.0#system-random-ctor(system-int32)

The example code uses:
(int) DateTime.Now.Ticks & 0x0000FFFF

There is no explanation why this is used. The example mentions the seeds generated might end up the same when executed too fast. Is this an example safety because Ticks changes from higher to lower bits?

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

@hexagonius it might be helpful if you attach the link to the page in question

When casting a long to int, the higher 32 bits are truncated, which means the seed value can change if the tick value changes. What’s the reason for masking the lower 16 bits?
