UserInfoResponse.previous_logon_time's value out of range of int

[ziay420]

After update Cloud Foundry, the previous_logon_time seems to change to 64bit value.

The reason caused this bug is UAA API returns a millisecond timestamp instead of a second timestamp. So previous_logon_time can't handle the value.

Thanks for the research, @ziay420, working on this now.
