It's called in:

        change_configuration_profile() (after reading the "recent" file, it's set to the value from that file)

        main(), if "-t" is specified;

        reftime_answered_cb() (if you answer "yes" to "Do you want to switch to "Seconds Since Beginning of Capture" 
now?")

        timestamp_format_cb() (when you explicitly set it through the GUI)

change_configuration_profile() is called only in profile_select() and select_profile_cb(), when you choose a profile.

The reason why it doesn't start out as TS_RELATIVE in Wireshark is, to quote the comment:

        so that "recent" in gtk/menu.c can detect this and distinguish it from a command line value

That refers to menu_recent_read_finished(), which sets recent.gui_time_format to the current time stamp value if it's 
not TS_NOT_SET, i.e., if it was set on the command line, that setting overrides whatever is in the recent file.

Is there some reason not to read the recent file *before* parsing the command-line arguments, so that we can just have 
the time stamp format initialized to TS_RELATIVE, override it from the recent file, and then possibly override *that* 
from the command line?
