Unit-testing a timezone based logic

Question

The America/New_York timezone is called EST in winter and EDT(in summer). Now my java program has a page that displays current time with the time zone as EDT.

To test the winter scenario, is there any way to manipulate the computer settings to simulate a winter scenario? Just to see if for a winter time, it displays EST proeprly?

Dependency inject the current time by passing it into your display.

For unittesting its not recommended to manipulate the system datetime, there are some workarounds to test date time based logic part.

Take alook at these threads:
