Last week, "Step 1: Assessment of Sponsor" for "Spouse, common-law partner or dependent child" was showing "68 days". Today, I was shocked to see "74 days".
However, close inspection reveals that if "(working on applications received on November 22, 2011)" were true, then it would be only 64 days from 2011-11-22 to 2012-01-25 (today).
Therefore, I suspect that the algorithm to calculate the number of days is misbehaving, and that the true number of days is "64 days" instead of "74 days".
Please let me know what is going on, and fix up the date-calculation algorithm, if necessary.
