One 're-fresh' of the 'Direct Trade/Cash Market' seemed to occur not long before this time (within an hour or less maybe):
reference:
Current UTC (or GMT/Zulu)-time used: Saturday, July 23, 2011 at 01:42:02
Another 're-fresh' time seems to be near 'Maintenance Mode', which would be roughly 8 hours after that time...somewhere close to 08:00 or 09:00 ("UTC" as above).
Also, maybe someone can post the 'error message' so it's more clear.
