# boot strap basic variable values, to drive Eclipse Platform builds.
# We set RAWDATE first thing, just to make it more accurate of the "start of the build".
# We have found on Hudson (but never by cron jobs) that by the time the build starts, it is often already 1 minute
# past the time we scheduled. This may eventually be fixed (or improved) in Hudson (see bug 496403).
# Initially we tried heuristic of deducting 60 seconds (bug 496345) but occasionally Hudson would start the job in, say 51 seconds, making
# our build ID a minute less that it should be. Then we tried 30 seconds (bug 500233), but given a look at the long term history
# of Hudson "start" times, it seems 30 seconds may fail at times too.
# So modified to truncate "epoch seconds" to the nearest 5 minutes since in our production builds we always schedule them
# to start at "even" times, such as "on the hour", occasionally "on the half hour", and rarely on "quarter hours" and maybe once at 10 after. :)
# So as long as schedule as it currently is, it seems truncating to nearest 5 minutes will always work. We have seen Hudson "delay times" range from
# about 20 seconds to at most about 2 minutes, but never any near 5 minutes so that shouldn't be a concern,
# unless Hudson delays start to get really long (over 5 minutes) for some reason.
