#OPSEC365 201/365
Timestamps reveal your timezone regardless of what you claim.
When you post at what you say is 9am but the metadata shows UTC offset, anyone can calculate your actual timezone. Photo timestamps, email headers, social media posts all carry timezone information. Someone tracking you can determine your general location from when you're active.
Consistent 3am activity on a US-based account suggests a different timezone than the one you claim.
