[General Issue] Change infinity value to "today in 200 years"

Describe your issue here

Infinity currently returns -1

Because of the lack of consistency in the return type, a datetime.datetime with the value "today in 200 years" should be returned.

[Bug in Parsing] Possible timezone parsing error with pytz library
Issue:

The pytz library has been known to cause issues when used in conjunction with datetime.timezone. As this is often used by other libraries, it is recommended to use the built-in zoneinfo library instead, which does not have these issues.

Important Note:

If you are using zoneinfo on a Windows machine, be sure to also install tzdata to ensure proper functioning.

Further information:
