Find Clock Sum

Need to total up a list of times but want more than just basic HH:MM math? The Find Clock Sum Tool goes further.

    • Decimal Hours – ideal for spreadsheets

  4. Enable or disable these toggles to control how input is processed:
    • Pad Output – adds leading zeroes to hours/minutes
    • Skip Invalid Lines – ignores lines that don’t match time format
    • Skip Empty Lines – ignores blank entries
    • Normalize Overflow Times – turns 1:75 into 2:15
