Bug in epoch-based timestamp parsing when month is not January

[c2d7fa]

Hey, thanks for making Decker, it's a lot of fun!

I may have found a bug in the date parsing function. This is on MacOS using version 1.43 of the Decker desktop application. When running this code in the listener (for example):

"%e" parse "2024-08-01T00:00:00Z"

I expect to get the output 1722470400, but instead I get 1704074580, corresponding to the date and time 2024-01-01T00:00:00Z. More generally, it seems that "%e" parse always ignores the month and instead returns the epoch timestamp corresponding to the given date if the month were set to January.
