Earlier class 7/26?

你好， 敬 轩，
对比 起。
   This comes at the last minute. I wonder if you have available class opening at 5 or 5:30 am Pacific time instead of 6:00 am? If not, no problem. I will meet with you then. There is an event at 6:20 I would like to attend, however, and if we can switch, I would be very grateful.

再 见，
