求救，lswrite写入载荷步时，会把time 1.000000005末位截掉？

比如有两条命令
time,0.990000005
.......
lswrite,1
time,1.000000000
.......
lswrite,2
time,1.000000005
.......
lswrite,3
lssolve,1,3
算到第三步时系统提示“Present time 1 is less than or equal to the previous time in a transient analysis. ”，好像lswrite命令写入的time变量有效位只有9位，第10位会被截掉,，怎么解决啊？
