Track Time In Zoho Projects or Invoices?

Track Time In Zoho Projects or Invoices?

Correct me if I'm mistaken, but Zoho Invoices doesn't sync time sheets with Projects, does it?

That is to say, if I track some time in Projects I can't see those entries within "Time Tracking" in Invoices.  And if I track some time in Invoices those entries aren't available to me within Projects.

Is this correct?
