#duration ⇒ Object (readonly)

NOTE: ‘time_since_offset` is used to produce start times timed phases of execution (validation, field resolution). These start times are relative to the executed operation’s start time, which is captured at the outset of document parsing.

The times produced are intentionally similar to: github.com/apollographql/apollo-tracing#response-format

Taking a field resolver start offset example:

< start offset > |——————|———-|———> OS (t=0) FS (t=1) FE (t=2)

OS = Operation start time FS = Field resolver start time FE = Field resolver end time
