I know that Palm OS sets the 24 hour interrupt so that it can advance the date
(there's no hardware date support, so Palm OS needs to keep track of that by
hand). However, while that goes off at midnight, I don't see it taking more than
a fraction of a second.

Subject: Palm OS does housekeeping at midnight?
I'm running a test on a module that spits out serial data - 3 messages - once
every second. I'm using a Palm (a Vx and a IIIc) to monitor these messages and
report if and when 1.5 seconds or more elapses between message transmissions. I
left the system running continuously over the weekend, starting on Friday
afternoon, with the error count reading 0. On Monday morning, the error count
was 3, Tuesday morning it was 4, and Wednesday morning it was 5. Wednesday, I
added a time stamp to the Palm display to discover when the time gap was
occurring, and restarted the system with an error count of 0. Thursday morning,
the error count was 1, with a time stamp of 0:00:03 (3 seconds past midnight).
The question: does Palm OS do some kind of memory garbage cleaning scheduled at
midnight that could take several seconds?
