+ <summary>

+ NetworkTimeTracker makes periodic queries to obtain a secure timestamp over

+ the network. This histogram records the delta between each secure timestamp

+ and the previous one, to measure how often time queries are made. The first

+ time query is not recorded, because there is no previous query from which to

+ compute a delta.
