Hi David,

Is there a method that allows access of Date and Time information from

I need to set the clocks on some remote devices, and they are all
attached through Modbus.  I need to preset a set of registers and then
trigger a 'load' command on the remote.

Yes, there's a stringin device support delivered as part of Base since
R3.14.5 that you can give an strftime string to. Eg:
record(stringin, "$(user)now")
{
    field(DESC, "Current time and date")
    field(DTYP, "Soft Timestamp")
    field(INP, "@%Y-%m-%d %H:%M:%S.%03f")
}
If you need the fields as integers rather than strings you can use one
stringin record per field and rely on the numeric conversions built into
the database links to convert the VAL field of each record into the
appropriate integer -- not wildly efficient, but functional.
