 2:: Introduce error but still noEmit
 Incremental build did not emit and has .ts as signature so exports has all imported modules/referenced files
 Clean build always uses d.ts for signature for testing thus does not contain non exported modules/referenced files that arent needed
+Clean build will not have dtsChangeTime as there was no emit and emitSignatures as undefined for files
+Incremental will store the past dtsChangeTime and emitSignatures

 13:: Fix error and no emit
 Incremental build did not emit and has .ts as signature so exports has all imported modules/referenced files
 Clean build always uses d.ts for signature for testing thus does not contain non exported modules/referenced files that arent needed
+Clean build will not have dtsChangeTime as there was no emit and emitSignatures as undefined for files
+Incremental will store the past dtsChangeTime and emitSignatures

+Clean build will not have dtsChangeTime as there was no emit and emitSignatures as undefined for files

 2:: Fix error and no emit
 Incremental build did not emit and has .ts as signature so exports has all imported modules/referenced files
 Clean build always uses d.ts for signature for testing thus does not contain non exported modules/referenced files that arent needed
+Clean build will not have dtsChangeTime as there was no emit and emitSignatures as undefined for files
+Incremental will store the past dtsChangeTime and emitSignatures
