add test to verify delay on local chain

[lucarlig]

example:

  it("should fail with start too early ", async () => {
    try {
      await program.methods
        .initializePeriodRegistry(start[0], period_length[1], n_periods[1])
        .accounts({
          owner,
          periodRegistry,
          systemProgram: SystemProgram.programId,
        })
        .rpc();
      expect(false, "should return an error");
    } catch (e) {
      console.log(e);
      expect(e, "wrong error returned").to.have.property("programErrorStack");
    }
  });

this isn't working probably local solana chain and computer time aren't synced properly, find a working solution to make such a test work
