timeSecs=
JavaTimeToGetSecs(javaTime, [updateInterval])
Convert time as reported by "java.lang.System.currentTimeMillis()" to
GetSecs units.
The Java timebase and
JavaTimeToGetSecs are used internally by
GetChar
because Java calls underlying
GetChar timestamp keyboard events in those
units.
updateInterval is the number of seconds before this function updates its
internal timing cache measuring the difference between
GetSecs and
java.lang.System.currentTimeMillis(). If set to -1, the cache is only
made the first time this function funs. When ommitted, it defaults to 0,
i.e., it recaches at every call.
