Just the time of the race but the name of the course in full e.g. Carlisle NOT Car or Carl.
I’ve also started to use the 24 hour clock as VTC does e.g. 1445 not 2.45. Not sure if this helps with the check or not 
This is not rocket science and may take an extra few seconds of your time posting your entry but I’m sure it will save a lot more of VTC’s
