The clock of OVZ node is not accurate, but provider refuse to correct it.

One of my openvz vps's clock is several minutes later than NTP clock, so I ask the provider to correct it on the Host Node, I told them if they don't like enable NTP on the node, at least run ntpdate once,

But they refuse to correct the clock, the reason is that they have many customers on the node, not only me, so they can't correct the clock for one person,

I can't understand this logic, is this an unreasonable request? I think that keep the node's clock accurate is the most basic principle in hosting industry, don't they think so?
