I have Truconversion, which is another heatmap product, but the team's development progress is slow, and the heatmap often displays incorrectly.

However, they have two key features:
1) The ability to assign specific websites to specific members.
2) The ability to freely assign a traffic limit for each website.

Additionally, you mentioned that the system's time zone is based on the website, but this seems incorrect. My time zone is GMT+8, yet the system appears to display all data in GMT+4.
