Then just set the ticks and the tick labels of the axis:

import numpy as np
import matplotlib.pyplot as plt
xdat=np.arange(1,11)
simtimedata = np.array([0, 1, 5, 9, 13, 18, 21, 24, 25, 28])
idatanp = np.array([-1,0, 1, 2, 3, 2, 1, 0, -1, -2])
ax1 = plt.subplot(111)
ax1.plot(xdat,idatanp)
ax2 = ax1.twiny()
ax2.set_xticks(range(len(xdat)))
ax2.set_xticklabels(simtimedata)
plt.show()
