Convert Cisco timestamps

Up to 500 values, separated by newlines, spaces or commas. Paste one numeric column, without a header or thousands separators.

For dateTimeConnect, choose “Not connected” to keep zero as an unset connection time.

Cisco exports seconds. Choose milliseconds only if your source uses them.

The Cisco CDR date/time fields

All three are unsigned integers holding a coordinated universal time (UTC) value: the number of seconds since midnight (00:00:00) Jan 1, 1970.

dateTimeOrigination

The time the call's originating device went off hook, or the time an outside call was first recognized by the system (it received the Setup message).

dateTimeConnect

The date and time the call was connected between the originating and terminating devices.

dateTimeDisconnect

The time the call was disconnected between the originating and terminating devices, or when the call was torn down even if it was never connected.

Stop converting CDRs by hand

PBXDom reads your Cisco call records continuously and turns them into live dashboards — no exports, no Epoch math.
