Patch in general looks good. I'm unsure about which way the timestamp
should be passed and parsed. I see 3 solutions:
1) Argument and use some standard function to parse date supply argument
+<value>
2) Essentially what you have done. It feels a bit ugly but not too much
3) Read directly from variable.
WDYT?

It's not worth spending a letter on this. Please keep only long version.
