in reply to binary clock from

Explicit loop and abusing $\ saves a few characters:

# 1 2 3 4 5 #12345678901234567890123456789012345678901234567890123456789 $\+=unpack("%32B*",pack"i3",gmtime$_)for(1..86400);print

    Parens could be ommited twice:
    # 1 2 3 4 5 #12345678901234567890123456789012345678901234567890123456789 $\+=unpack"%32B*",pack"i3",gmtime$_ for 1..86400;print
    My shortest approach:
    # 1 #123456789012345 print 682560
      which can be further shortened by using perl -d. Also, this version doesn't entail knowing the answer in advance:
      # 24*2*60*(64*3-20)+60*60*(8*2+4*3*3) # =2880*(4*43+5*13) # =2880*237 # 1 2 3 #123456789012345678901234567890123456789 p 8640*79
