The number of seconds between an attempt to fetch an ad creative and when the first frame of an ad creative played in the selected time period.

Note: According to the SDK behavior, the ad's session is created after the content session is created. VST is the time taken to load the actual video minus the ad playtime. Hence it includes the AST. For client-side ads, VST is more than AST. For server-side ads, since the ads and content are stitched into a single stream, AST is short.
