HHSE never implied a 60-day "continuous" audit process, and neither did the auditor to HHSE. It was blogged that the library valuation came in "higher than expected" (not quite an abduction by aliens, but an equally unexpected event). This constituted an "interruption" of that 60-day process, to be resumed as soon as an agreement is reached between management and Library Valuation provider with a reasonably accurate library valuation.
In other words, the only "reasonable" conclusion is that the auditor waiting for the library valuation results caused the 60-day clock to "PAUSE".
