/** A RepeatTime represents a r= field contained within a TimeDescription.
*
* A RepeatTime specifies the repeat times for a SessionDescription.
*
* This consists of a "repeat interval", an "active duration", and a list of offsets relative to the t=
* start-time (see Time.getStart()).
*
* Quoting from RFC 2327:
*
* For example, if a session is active at 10am on Monday and 11am on Tuesday for
* one hour each week for three months, then the in the corresponding
* "t=" field would be the NTP representation of 10am on the first Monday, the
* would be 1 week, the would be 1 hour, and
* the offsets would be zero and 25 hours. The corresponding "t=" field stop time
* would be the NTP representation of the end of the last session three months later.
* By default all fields are in seconds, so the "r=" and "t=" fields might be:
*
* t=3034423619 3042462419
* r=604800 3600 0 90000
*
*
* Please refer to IETF RFC 2327 for a description of SDP.
