Library for time zone conversions and automatic DST adjustments

HELLO!
I have some questions about this library and RTC library of arduino IDE.

so i work in a project in which i use the ds1307 module and i want to use both libraries, can i do that with out any problem?

An other question is; if i write the code for the ds1307 could i replace the ds1307 with ds3231 without changes in the code?

Thank you in advance.
