Subject:	SGP/MFRSR/E12 - Incorrect times
DataStreams:	sgpmfrsrE12.a0, sgpmfrsrE12.b1, sgpmfrsrlangleyE12.c1, sgpmfrsrE12.00, sgpmfrsrlangplotE12.c1
Description:	The ntpd server (time adjustment) stopped working on Feb. 19th at 22:12:16 GMT, and the clock was corrected by -5600.177269 seconds on March 10th at 22:47 GMT. The recorded times for observations are off by amounts ranging from 0 seconds on Feb. 19th to 5600 seconds on March 10th.
Suggestions:	Observation times might be improved somewhat by estimating an interpolated time drift using sunrise/sunset event timings in the shortwave channels.
