- Field Detail
  - NTP_CONST
```
static final 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. 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.
