A data frame. The |
The COLSRC data frame of an MTZ header has a column called
created
which displays the date and time at which the
MTZ file data columns were created. When writing out a
modified list obtained from reading an MTZ file, one might
want to change the created
column with the current
date and time. Other specific types of change can be operated
by handling the COLSRC
data frame in an *ad hoc* manner.
The hdr

column of the COLSRC
data frame changed to
display the current date and time.
