Sodium Thiosulfate Reaction Time with HCl vs. Sulfuric Acid

[Zibi04]

Was wondering if there is a difference in time of reaction between sodium thiosulfate with HCl and sodium thiosulfate with sulfuric acid.
If so, what is this difference and why does this occur?

Have you tried to find what is the mechanism of the reaction? Or what is its observed kinetics? Answer can be just a google away.
