[rrd-users] question on lastupdate

[Ivan Matveyev]

Experimenting with possible load for my applications, I met the following.
When creating an rrd file with such options:

Array
(
    [0] => --step
    [1] => 900
    [2] => --start
    [3] => 0
    [4] => DS:tg_in_calls:GAUGE:1200:0:U
    [5] => DS:tg_in_calls_uns:GAUGE:1200:0:U
    [6] => DS:tg_in_reason_0:GAUGE:1200:0:U
    [7] => DS:tg_in_reason_1:GAUGE:1200:0:U
    [8] => DS:tg_in_reason_2:GAUGE:1200:0:U
    [9] => DS:tg_in_reason_3:GAUGE:1200:0:U
    [10] => DS:tg_in_reason_4:GAUGE:1200:0:U
    [11] => DS:tg_in_reason_5:GAUGE:1200:0:U
    [12] => DS:tg_in_reason_6:GAUGE:1200:0:U
    [13] => DS:tg_in_reason_7:GAUGE:1200:0:U
    [14] => DS:tg_in_reason_8_15:GAUGE:1200:0:U
    [15] => DS:tg_out_calls:GAUGE:1200:0:U
    [16] => DS:tg_out_calls_uns:GAUGE:1200:0:U
    [17] => DS:tg_out_reason_0:GAUGE:1200:0:U
    [18] => DS:tg_out_reason_1:GAUGE:1200:0:U
    [19] => DS:tg_out_reason_2:GAUGE:1200:0:U
    [20] => DS:tg_out_reason_3:GAUGE:1200:0:U
    [21] => DS:tg_out_reason_4:GAUGE:1200:0:U
    [22] => DS:tg_out_reason_5:GAUGE:1200:0:U
    [23] => DS:tg_out_reason_6:GAUGE:1200:0:U
    [24] => DS:tg_out_reason_7:GAUGE:1200:0:U
    [25] => DS:tg_out_reason_8_15:GAUGE:1200:0:U
    [26] => RRA:AVERAGE:0.5:1:100000
    [27] => RRA:MIN:0.5:1:100000
    [28] => RRA:MAX:0.5:1:100000
)

I am getting file with lastupdate in the beginning of the current day:

<!-- Round Robin Database Dump -->
<rrd>
        <version> 0001 </version>
        <step> 900 </step> <!-- Seconds -->
        <lastupdate> 1077742800 </lastupdate> <!-- 2004-02-26 00:00:00 MSK
-->

I need to update this rrd with values dated 1 december 2003. So, I'm
getting "UPDATE ERROR occurred: illegal attempt to update using time
1070226900 when last update time is 1077742800 (minimum one second step)"

RRDtool 1.0.40

Any recommendations?
