I am using the package mathptmx to change the text font to Times. However, the mathcal font is changed as well, which is think is a bit ugly.
How can I reset the mathcal font to its default?

Use only \renewcommand\rmdefault{ptm} instead of your package.
You can also use a font package like newtxtext (as suggested by Manual), or tgtermes, or even times (which would also change the sans serif and the tt). All of them affect only the text font.
You can achieve your objective as follows:
Don't load the
timespackage, as it is deprecated. Load the packagemathptmxinstead. (Or, if you prefer, load the packagesnewtxtextandnewtxmath.)Load the
helvetpackage with the optionScaled. In my opinion, the default amount of scaling that's applied isn't quite right for use with theTimestext font if you want the x-heights of the serif and sans-serif letters to line up. I'd therefore use the optionScaled=0.86.
Incidentally, the font employed by mathsf in your example is not Helvetica but Computer Modern Sans Serif.
\documentclass[11pt]{article}
\usepackage{mathptmx}
\usepackage[scaled=0.86]{helvet}

Addendum: I had assumed -- possibly erroneously -- that because you loaded the package times, you wanted to use Helvetica as the document's sans serif font. If this assumption is incorrect, i.e., if you simply want to use Computer Modern Sans Serif (CMSS) along with Times New Roman (TNR), don't load the helvet package -- and definitely don't load the times package since it sets up Helvetica as the sans serif font. It so happens that the x-heights of TNR and CMSS are fairly similar; there is hence no need to scale CMSS to make it "work" alongside TNR.
