"how long takes it to build a compiler?"

Or, in other words: If you do not invent your own language, but have
to implement according to some given specifications, be prepared to
spend quite some on understanding these specs and all the involved
ramifications.


Implementing "a pascal-like compiler" with convenient restrictions
is likely to scale according to the 90/90 rule.
