Time zones

Charts time zone handling

AppMon charting does not handle time zones, and the first day of the week is fixed as Monday. This may result in unexpected behavior when people in different time zones visualize charts.

AppMon Server interprets time frames and aggregates time series. In AppMon Client, an offset shifts time stamps when AppMon Client and server time zones differ.

Possible pitfalls with time frames

Time frames like Today, Yesterday, This Week, Last Week, This Month, and Last Month are also evaluated by the AppMon Server. So data for the respective time span in server time zone is returned and shows in the AppMon Client.

Time Frame Description
Today, This Week, This Month AppMon Client uses its own time zone to visualize a time range. However, data aggregates using AppMon Server time.
Last X Time Range Data shifts by time zone difference.


AppMon Server location Linz, AT (GMT+01:00) (GMT = Greenwich Mean Time = UTC)
AppMon Client location Boston, US (GMT-05:00)
Time frame today
Current Time Linz 19-Nov 2009 2:15 pm
Current Time Boston 19-Nov 2009 8:15 am
Today timeframe in Boston will show 18-Nov 2009 6:00 pm to 19-Nov 2009 8:15 am

When charting a measure, the AppMon Client shows chart data from 18-Nov 2009 - 6:00 pm to now (19-Nov 2009 - 8:15 am), as the today time frame gets evaluated in server time zone (GMT+01:00) and 19-Nov 2009 - 00:00 am to 19-Nov 2009 - 2:15 pm in GMT+01:00 equals 18-Nov 2009 - 6:00 pm to 19-Nov 2009 8:15 am in GMT-05:00.
