    Hi Reza,

    Your problem is the dates and times,

    Your original trace begin the record on JAN 01 (001), 1983, 12:06:24.194

    and you want setting an origin time on 1982 123 13 37 10 103,

    so, only for test, sac write the header O, you can not see the mark because it
    is out of the trace time window.

    See the O marker in second header.

    HTH,

    Milton
