| javax.sdp.TimeDescription
| TimeDescription | | public interface TimeDescription extends Serializable,Cloneable(Code) | | A TimeDescription represents the fields present within a SDP time description.
Quoting from RFC 2327:
Multiple "t=" fields may be used if a session is active at multiple
irregularly spaced times; each additional
"t=" field specifies an additional period of time for which the session
will be active. If the session is active at
regular times, an "r=" field (see below) should be used in addition to and
following a "t=" field - in which
case the "t=" field specifies the start and stop times of the repeat sequence.
Please refer to IETF RFC 2327 for a description of SDP.

| Field Summary | |
| final public static long | NTP_CONST
Constant used to translate between NTP time used in SDP and "native" Java time.
NTP time is defined as the
number of seconds relative to midnight, January 1, 1900 and Java time is
measured in number of milliseconds
since midnight, January 1, 1970 UTC (see System#currentTimeMillis()}).
The value of this constant is 2208988800L. |
| Method Summary | |
| public Vector | getRepeatTimes(boolean create)
Returns the list of repeat times (r= fields) specified in the SessionDescription. | | public Time | getTime()
Returns the Time field. | | public void | setRepeatTimes(Vector repeatTimes)
Returns the list of repeat times (r= fields) specified in the SessionDescription. | | public void | setTime(Time t)
Sets the Time field. |
| NTP_CONST | | final public static long NTP_CONST(Code) | | Constant used to translate between NTP time used in SDP and "native" Java time.
NTP time is defined as the
number of seconds relative to midnight, January 1, 1900 and Java time is
measured in number of milliseconds
since midnight, January 1, 1970 UTC (see System#currentTimeMillis()}).
The value of this constant is 2208988800L. It can be used to convert between
NTP and Java time using the
following formulas:
ntpTime = javaTime/1000 * SdpConstants.NTP_CONST;
javaTime = (ntpTime - SdpConstants.NTP_CONST) * 1000;
The Network Time Protocol (NTP) is defined in RFC 1305.
