What is the local timezone on the server ? I'm guessing that since your email says +4, your server might be set to +3 and this would account for your problem. RRD uses UTC, and all steps are aligned on Unix epoch (ie "start of time" at midnight 1st Jan 1970). Hourly/daily etc steps will always be aligned on midnight UTC. It's been discussed regularly in the past, but I can't recall what teh answer was. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
