CDR Timestamps and Dates

The CDR data schema is provided with basic definitions. As with past OE
releases, the StartTime, EndTime, and other timestamps in the OE 4.0 CDR
database are in seconds and are offset numbers from a standard industry
reference point of January 1, 1970 UTC. A reporting tool must compute the
actual date and time for use in reports. When writing a program from C, the
standard function call would be to: ctime (&1time) where &1time points to
the UTC value (for example, 768027063). The call returns the Unix time
and date (Wed May 04 04:51:03 1994).

Start time

• Start time can vary depending on the use and configuration of
AltiWare for CO trunks.
• Start time will be a few seconds (typically two) after incoming trunk
seizure if the incoming trunk type is a tie trunk or an analog or T1 C.O.
trunk not supporting Caller ID or ANI signaling.
• Start time will be seven (7) seconds or more if the incoming analog or
T1 trunk supports Caller ID/ANI since the Central Office (CO) first
sends these digits between the first and second ring cycles before the
target device is to be connected. This is good, since carrier billing does
not start until the target device answers.
• Start time for outgoing trunks is immediately when AltiWare attempts
to seize an outgoing trunk; hence even for outgoing calls that hit an all
trunks busy signal.
