If you select an ICS from either the WinBoard Startup dialog or the
Windows Start submenu that WinBoard installs, WinBoard automatically
runs timestamp or timeseal if the ICS you chose is known to support it.
If you are constructing a WinBoard command line by hand, add the option
"/icshelper timestamp" or "/icshelper timeseal" to the WinBoard command
line to use timestamp or timeseal. Both timestamp.exe and timeseal.exe
are included in the WinBoard distribution. They both function
identically to the Unix versions, as documented in "help timestamp" on
ICC and "help timeseal" on FICS.
If you have a firewall between your machine and the ICS, see topic
If you normally have to use the "/icscomm" command line option on
WinBoard to log into a shell account, and then telnet to ICC or FICS
from there, you are going to have to run the Unix version of timestamp
or timeseal on the shell machine. (If the shell account is not on a Unix
machine, you are out of luck.) Get the appropriate version of timestamp
or timeseal onto the shell machine via FTP; see the help files on ICC
and FICS for instructions. Then simply run it when you would normally
run telnet. In this configuration you are not protected against lag
between your PC and the shell machine, or for lag caused by heavy load
on the shell machine itself from other users.
For further information on timestamp and timeseal, see the help files on
ICC and FICS.
