Note that timedate.cpl is not a command line tool and does not have any parameters. It is the command for opening "Date and Time" user interface.
rundll32.exe shell32.dll,Control_RunDLL
timedate.cpl,,/Z Central Standard Time
In this command timedate.cpl does not take any parameters. This command uses timedate.cpl as a parameter.
The command used to manage time and zone options is "w32tm.exe" and here are the parameters for it. If you tell what you are trying to do, I can help.
w32tm [/? | /register | /unregister ]
register - register to run as a service and add default configuration to the registry.
unregister - unregister service and remove all configuration information from the registry.
w32tm /monitor [/domain:
]
[/computers:[,[,me>...]]]
[/threads:] [/ipprotocol:<4|6>] [/nowarn]
domain - specifies which domain to monitor. If no domain name is given, or neither the domain nor computers option is specified, the default domain is used. This option may be used more than once.
computers - monitors the given list of computers. Computer names are separated by commas, with no spaces. If a name is prefixed with a '*', it is treated as an AD PDC. This option may be used more than once.
threads - how many computers to analyze simultaneously. The default value is 3. Allowed range is 1-50.
ipprotocol - specify the IP protocol to use. The default is to use whatever is available.
nowarn - skip warning message.
w32tm /ntte
Convert a NT system time, in (10^-7)s intervals from 0h 1-Jan 1601, into a readable format.
w32tm /ntpte
Convert an NTP time, in (2^-32)s intervals from 0h 1-Jan 1900, into a readable format.
w32tm /resync [/computer:] [/nowait] [/rediscover] [/soft]
Tell a computer that it should resynchronize its clock as soon as possible, throwing out all accumulated error statistics.
computer: - computer that should resync. If not specified, the local computer will resync.
nowait - do not wait for the resync to occur; return immediately. Otherwise, wait for the resync to complete before returning.
rediscover - redetect the network configuration and rediscover network sources, then resynchronize.
soft - resync utilizing existing error statistics. Not useful, provided for compatibility.
w32tm /stripchart /computer: [/period:]
[/dataonly] [/samples:] [/packetinfo] [/ipprotocol:<4|6>]
Display a strip chart of the offset between this computer and
another computer.
computer: - the computer to measure the offset against.
period: - the time between samples, in seconds. The
default is 2s
dataonly - display only the data, no graphics.
samples: - collect samples, then stop. If not
specified, samples will be collected until Ctrl-C is pressed.
packetinfo - print out NTP packet response message.
ipprotocol - specify the IP protocol to use. The default is
to use whatever is available.
