Time IS a system of assigning dates/hours.
Measuring intervals is its less important,
secondary functionality. It's not optmized
for that and it doesn't have to be optimized
for that.
NO!!!
You have to distiguish between time (which is the physical phenomenon you like to measure) and the measurement of that quantity.
Time belongs to nature and exists there for uncertain reasons.
The measurement of time utilises clocks of various kinds, which do NOT belong to nature (because they are artifacts).
So: natur does not know anything about hours and seconds and uses other other means than clocks.

No. It's 18th march 2024. Most people are unable
to calculate the interval between 2024-03-18
and 0001-01-01 correctly. And they don't need
it at all.
Sure, most people cannot do that without a calculator. But if you need that number, you find various calculators, which can  answer that question in less than a second.
