what happens between the timestamp 'Date Sent' and 'Execute from'

Hi all,

from SXMB_MONI, I found that some messages take a long time, for example:

Date Sent 23.09.2008 02:22:39

Time Taken to Process (Secs) 0,5044590

Execute From 23.09.2008 02:23:12

To 23.09.2008 02:23:13

Status Set 23.09.2008 02:23:13

you can find that there are about 30s between the 2 timestamps.

does anybody know what does the timestamp 'Date Sent' mean? and what does the 'Execute From' mean?

what happens between these 2 timestamps?

Regards,

Bean
