  • [General Issue] Change infinity value to

    [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

    [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:
