Here are some other suggestions. Your suggestions, as far as formality goes, were a little hit-and-miss.
1. I'm looking forward to the interview.
2. Would this Thursday, January 30 your time, or Friday the 31st be suitable for you?
If the interviewer's Thursday is the same as yours, then "your time" isn't needed.
3.Thursday morning between 9 and 12 your time may be better, as it will be evening in my country and the network connection is more reliable then.
Note: 12am is midnight. 12pm is midday.
4. My time zone is 13 hours ahead of yours.
Your sentence was a little confusing - it sounded like the interviewer lives east of you, not west (according to time zones). I guess your interviewer is on the east coast of the US?
