This is true. I was basically forced into admitting "15 minutes" of field service time one month. I guess the Secretary couldn't bear the thought of me being irregular.
I remember my the elders stopping by and basically trying to get my mom to submit at least one hour during several months when she was traveling back and forth a lot to help her dying father. They would ask "What about the family study?" and she would tell them that she had the oldest child conduct it. Then they would ask if she talked to anyone while she was traveling and she tell them no and that she used that time to catch up on sleep. Then they would ask if she talked about anything spiritual with her kids or UBM or clients at work or anyone because 3 months had gone by and she had not turned in any time.
That's when she got upset. My mom was so dog tired from working, a house full of kids and a husband to care for and her last living parent that lived across the country was dying. She snapped and told them that she didn't have any time and asked what more did they want...for her to lie. Then Br. S told her not to worry, they would just submit 1 hour for each month because they were sure she had time but was to probably too distressed to remember.
Same thing with me as a pioneer. I was traveling a lot for work and they saw me in service when I was town but did not turn in my time for two months and then I gave it to the secretary mid month while I remembered. He told me I wasn't missing any time. Evidently someone had simply duplicated my time from the last reported month for the next two. But that also meant that someone had banked 30+ phantom hours for me. Like an idiot I actually made up the phantom hours.
