In MIPS programs related traces the following timestamp resetting events happen:

262 clk 0 IT (262) ffffffffbfc0ff30 nop
263 clk 0 IT (263) ffffffffbfc0ff34 nop
264 clk 0 IT (264) ffffffffbfc0ff38 nop
265 clk 0 IT (265) ffffffffbfc0ff3c nop
266 clk 0 IT (266) ffffffffbfc0ff40 nop
267 clk 0 IT (267) ffffffffbfc0ff44 nop
268 clk 0 IT (268) ffffffffbfc0ff48 nop
269 clk 0 IT (269) ffffffffbfc0ff4c nop
270 clk 0 IT (270) ffffffffbfc0ff50 nop
271 clk 0 IT (271) ffffffffbfc0ff54 nop
272 clk 0 IT (272) ffffffffbfc0ff58 nop
273 clk 0 IT (273) ffffffffbfc0ff5c nop
274 clk 0 IT (274) ffffffffbfc0ff60 nop
0 clk 0 IT (0) ffffffffbfc0ff64 nop
1 clk 0 IT (1) ffffffffbfc0ff68 nop
2 clk 0 IT (2) ffffffffbfc0ff6c nop
3 clk 0 IT (3) ffffffffbfc0ff70 nop
4 clk 0 IT (4) ffffffffbfc0ff74 nop
5 clk 0 IT (5) ffffffffbfc0ff78 nop
6 clk 0 IT (6) ffffffffbfc0ff7c nop
7 clk 0 IT (7) ffffffffbfc0ff80 nop
8 clk 0 IT (8) ffffffffbfc0ff84 nop
9 clk 0 IT (9) ffffffffbfc0ff88 nop

It looks like the trace contains a number of similar fragments of the same execution. The timestamp value should grow steadily, without any resets.
