From: Wunderlich, Mark <mark.wunderlich@xxxxxxxxx>
[ Upstream commit ddef29578a81a1d4d8f2b26a7adbfe21407ee3ea ]
Allow the do/while statement to continue if current time
is not after the proposed time 'deadline'. Intent is to
allow loop to proceed for a specific time period. Currently
the loop, as coded, will exit after first pass.
