-pppd: Watch out for time warps
-
-On many embedded systems there is no battery backed RTC and a proper system
-time only becomes available through NTP after establishing a connection.
-
-When the clock suddenly jumps forward, the internal accounting (connect time)
-is confused resulting in unreliable data.
-
-This patch implements periodic clock checking to look for time warps, if one
-is detected, the internal counters are adjusted accordingly.
