Changing days does not always work

Wes reports:
At the changeover in UTC day, I can see spectrograms for the 3 hours prior. Next I click the daily mosaic, which brings up the current UTC day. Between 00:00 UTC and 00:10 UTC (actual time) I see no spectrograms for the current UTC day. This is certainly the expected behavior. But when I try to click back in time, to go to the previous UTC day, I'm unable to. The page reloads, but it is still the current UTC day. At 00:10 UTC, the first spectrogram for the new day is generated and everything works as expected.
