Subtraction assignment operators

== Synopses

Declared in `&lt;bsls&lowbar;timeinterval&period;h&gt;`

Subtract from this time interval the value of the specified `rhs` real number of seconds, and return a reference providing modifiable access to this object&period; The fractional part of `rhs`, if any, is rounded to the nearest whole number of nanoseconds before being subtracted from this object&period; The behavior is undefined unless `rhs` can be converted to a valid `TimeInterval` object whose `seconds` field is greater than `LLONG&lowbar;MIN`, and the total number of seconds in the resulting time interval can be represented with a 64&hyphen;bit signed integer&period;
