Subject: epics-3.14/seq2.0.2 on pc104 card running linux

We've been playing around with the latest  epics base (3.14) and seq2.0.2 on a pc104 card running linux.    We've been having difficulty getting the sequencer to work.  At first we thought is was due to  some incompatibilities between the desktop linux machine that compiled the code and the pc104 card.   After many "printf" insertions into the code,  we found that sequencer was getting stuck in pthread_cond_timedwait.

Printing out the tv_sec and tv_nsec  elements of wakeTime  showed that we had the wrong date set on the pc104 and the tv_sec element was returned as a negative value from convertDoubletoWakeTime.

Correctly setting the date, fixed the problem......

Not sure what the moral is,  nor have I looked into convertDoubletoWakeTime to see if the code can be fixed to work with unreasonable "pre-epics-epoch" dates.

Make sure  your ioc's boot with the correct date........
